Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an information processing apparatus and method, and more particularly to an information processing apparatus and method using a 3D model (3D shape) created using 3D-CAD.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a CAD device (particularly, a 3D-CAD device) has been used to design an article (hereinafter, simply referred to as a component) having a three-dimensional shape, such as a product or a component constituting a product.
[0003]
In addition, based on this design, a mold for producing parts was manufactured.
[0004]
In using design information created by a CAD device, attribute information such as dimensions, dimensional tolerances, geometrical tolerances, notes, and symbols has been input to a 3D model (3D shape).
[0005]
In order to input attribute information to the 3D model, it is performed by specifying and selecting a surface, a ridge line, a center line, a vertex, or the like of the 3D model. For example, in a 3D model as shown in FIG. 24 (a front view, a plan view, and a side view of this 3D model are shown in FIG. 25), attribute information is input as shown in FIG. 26, for example. Here, the attribute information is
Dimensions such as distance (length, width, thickness, etc.), angle, hole diameter, radius, chamfer, etc., and dimensional tolerances associated with the dimensions
Geometric and dimensional tolerances added to faces, ridges, etc. without entering dimensions
A note that should be conveyed or instructed in processing or producing parts, units or products.
Symbols such as surface roughness that are determined in advance as a convention.
[0006]
The method of attaching attribute information to the 3D model is roughly classified into the following two types.
[0007]
(1) When dimensions, dimensional tolerances, geometric tolerances, notes, and symbols are given
Dimension lines and extension lines are required to enter dimensions and dimensional tolerances
Leader lines required to fill geometric tolerances, notes, and symbols
(2) When dimensions are not added and dimensional tolerances, geometrical tolerances, notes, and symbols are added
No dimension lines or extension lines required
Leader lines required to fill dimensional tolerances, geometric tolerances, notes, and symbols
In addition, a mold was manufactured using a 3D model. In this case, it was necessary to inspect whether the manufactured mold and the molded product molded by the mold were completed as designed.
[0008]
[Problems to be solved by the invention]
The method of attaching attribute information to a 3D model as in the above conventional example has the following problems.
[0009]
In the case of the above (1), dimensions and dimensional tolerances, and dimension lines and dimension auxiliary lines for writing them are complicated, and it becomes difficult to see the shape and attribute information of the 3D model.
[0010]
As shown in FIG. 24, if the number of pieces of attribute information is relatively tens and the number of pieces of attribute information is about several tens, it can be managed. Attribute information is added to the 3D model, so that "the attribute information overlaps", "the attribute information overlaps with the dimension line, dimension auxiliary line, or leader line", "dimension line, dimension auxiliary line, or leader line" It is very difficult to read the attribute information (even the step shape at the corner in FIG. 26 is somewhat difficult to see).
[0011]
In such a case, it is difficult for the operator who inputs the attribute information to see the input information, and the input content cannot be confirmed, that is, the input of the attribute information itself becomes difficult.
[0012]
In addition, it becomes extremely difficult to read related attribute information. In addition, the space occupied by the attribute information becomes larger than the 3D model, and it becomes impossible to simultaneously view the shape of the 3D model and the attribute information on a display screen having a limited size.
[0013]
Furthermore, attribute information to be indicated in a so-called cross-sectional view or the like (for example, the counterbored hole depth of 12 ± 0.1 in FIG. 24) is difficult to understand because the indicated position of the 3D model is not visible.
[0014]
The fine and complicated partial shape of the 3D model is enlarged so as to be in a display state in which the shape can be sufficiently understood, and the dimensions and the like are set to appropriate sizes in this display state. However, the dimensions and the like set in this way become small when the display magnification is reduced and the whole is displayed, and there is a problem that it is necessary to find these dimensions carefully when viewing these dimensions. . In the worst case, there is a problem that erroneous processing or the like is performed without noticing the attached dimensions and the like. Furthermore, when viewing a fine and complicated partial shape and dimensions of the 3D model, there is a problem that the dimensions and the like attached to the entire shape are displayed extremely large and are difficult to see.
[0015]
In the case of the above (2), the dimension line and the dimension auxiliary line are unnecessary, but since the lead line is used, the lead line becomes complicated similarly to the above (1), and the shape and the attribute information of the 3D model are reduced. It will be difficult to see. Further, in the case of a complicated shape or a large shape, since hundreds to thousands of attribute information are added to the 3D model as needed, it becomes extremely difficult to read the attribute information.
[0016]
In addition, it is necessary to measure dimensions and the like when inspecting a completed mold and a molded product formed by the mold, for example. Therefore, in order to read the dimension value, a measurement operation using a measurement function of the 3D model shape is required.
[0017]
In this case, it is necessary to specify and select a reference position of a dimension for a portion to be read, such as a ridge line. When reading a plurality of dimensions, a large number of operations and a long operation time are required. It is a mess. In addition, the possibility of misreading due to an operation error is inevitable. Further, when reading the dimensions of all parts, extremely enormous labor is required.
[0018]
In the first place, the 3D model and the attribute information are information for processing and manufacturing parts, units, and products, and the information can be understood from the input operator = designer to the viewing operator = engineer of processing, manufacturing, inspection and the like. It must be easy, efficient, and communicated without error. In the above-mentioned prior art, these are not satisfied at all, and it is not a form which can be used industrially effectively.
[0019]
Therefore, an object of the present invention is to easily, easily and efficiently add, display, and view attribute information such as dimensions to data created by a CAD device or the like.
[0020]
Another object of the present invention is to efficiently use the added attributes.
[0021]
Another object of the present invention is to efficiently create a part utilizing data created by a CAD device or the like.
[0022]
It is another object of the present invention to efficiently perform an inspection process using data created by a CAD device or the like.
[0023]

[0033]
BEST MODE FOR CARRYING OUT THE INVENTION
(Embodiment 1)
An embodiment of the present invention will be described in detail with reference to the drawings.
[0034]
First, the “entire flow of mold production” will be described.
[0035]
FIG. 1 is a diagram showing an overall flow when the present invention is applied to production of a mold part mold.
[0036]
In the figure, in step S101, a product is designed and a design drawing of each part is created. The component design drawing includes information necessary for component production, constraint information, and the like. The design drawing of the part is created by 2D-CAD or 3D-CAD, and the drawing created by 3D-CAD (3D drawing) includes attribute information such as shape and dimensional tolerance. The dimensional tolerance can be associated with the shape (surface, ridgeline, point), and the dimensional tolerance is used for an instruction for inspecting a molded product, an instruction for mold accuracy, and the like.
[0037]
In step S102, a study of manufacturability such as assembling and molding of a product is performed, and a process diagram for each component is created.

[0038]
Here, examples of detailed inspection instructions include numbering of measurement items (dimensions or dimensional tolerances), measurement point and measurement method instructions for measurement items, and the like.
[0039]
Detailed inspection instruction information can be associated with dimensional tolerances on CAD.
[0040]
In step S103, a mold is designed based on the process drawing (process drawing, mold specification) of the component created in step S102, and a mold drawing is created.

A mold drawing is created by 2D-CAD or 3D-CAD, and a mold drawing (3D drawing) created by 3D-CAD includes attribute information such as shape and dimensional tolerance.
[0041]
In step S104, the mold manufacturing process is examined based on the mold drawing created in step S103, and a mold process drawing is created. The mold processing step includes NC processing and general-purpose processing. For the process of performing NC processing (automatic processing by numerical control), an instruction to create an NC program is issued. In the general-purpose processing (manual processing) step, an instruction for performing general-purpose processing is issued.
[0042]

[0047]
In step S110, based on the result of the inspection in step S109, the mold of the part of the molded product with insufficient accuracy is corrected.
[0048]
Next, “product design” will be described.
[0049]
The design of a product and the creation of design drawings for individual parts will be described. The design drawing of the part is created by a 2D-CAD device or a 3D-CAD device.
[0050]
Here, the design of parts will be described using the information processing apparatus shown in FIG. 2, for example, a CAD apparatus.
[0051]
FIG. 2 is a block diagram of the CAD device. In the figure, reference numeral 201 denotes an internal storage device, and 202 denotes an external storage device, which comprises a semiconductor storage device such as a RAM for storing CAD data and a CAD program, a magnetic storage device, and the like.
[0052]
Reference numeral 203 denotes a CPU device that executes processing in accordance with the instructions of the CAD program.
[0053]
Reference numeral 204 denotes a display device which displays a shape or the like in accordance with a command from the CPU device 203.
[0054]
Reference numeral 205 denotes an input device such as a mouse or a keyboard for giving an instruction or the like to the CAD program.
[0055]
Reference numeral 206 denotes an output device such as a printer that outputs a paper drawing or the like in accordance with an instruction from the CPU device 203.
[0056]
An external connection device 207 connects the CAD device to an external device, supplies data from the device to the external device, and controls the external device from the external device.
[0057]
FIG. 3 is a flowchart showing a processing operation of the CAD apparatus shown in FIG.
[0058]
First, when the operator instructs the activation of the CAD program by the input device 205, the CAD program stored in the external storage device 202 is read into the internal storage device 201, and the CAD program is executed on the CPU device 203 (step S301).
[0059]
When the operator interactively instructs using the input device 205, a shape model is generated on the internal storage device 201 and displayed as an image on the display device 204 (step S302). This shape model will be described later. When the operator specifies a file name or the like with the input device 205, the shape model already created on the external storage device 202 can be read into the internal storage device 201 so that the CAD program can handle the shape model.
[0060]
The operator creates an attribute arrangement plane in the three-dimensional space in which the shape model has been created using the input device 205 (step S303).
[0061]
The image is displayed on the display device as image information such as a frame (double frame, fill in frame) or the like so that the position of the attribute arrangement plane can be easily determined. The setting information of the attribute placement plane is stored in the internal storage device 201 in association with the shape model.
[0062]
It is desirable to name the created attribute arrangement plane as needed.
[0063]
The operator adds dimensional tolerance and the like as attribute information to the shape model using the input device 205 (step S304). The added attribute information can be displayed on a display device as image information such as a label. The added attribute information is stored in the internal storage device 201 in association with the shape model.
[0064]
The operator associates the attribute information with the attribute arrangement plane using the input device 205 (step S305).
[0065]
The attribute information and the related information of the attribute arrangement plane are stored in the internal storage device 201.
[0066]
The operator may designate an attribute placement plane in advance, and perform attribute assignment while associating with the attribute placement plane. Further, the operator can use the input device 205 to set and cancel the association of the attribute information with the attribute arrangement plane.
[0067]
Next, the operator specifies display of the attribute placement plane and display / non-display of attribute information such as dimensional tolerance associated with the attribute placement plane by specifying the attribute placement plane by the input device 205, or display control such as coloring. Perform (Step S306).
[0068]
When the operator creates an attribute placement plane using the input device 205, the operator sets the position of the viewpoint, the line-of-sight direction, and the magnification of the attribute placement plane. By setting the attribute placement plane display information and designating the attribute placement plane, the shape model can be displayed with the set viewpoint position, viewing direction, and magnification. Further, since the attribute placement plane is associated with the attribute information, the attribute information associated with the designated attribute placement plane can be selectively displayed. The attribute arrangement plane display information is stored in the internal storage device.
[0069]
According to the instruction of the operator, the attribute information can be stored in the external storage device 202 or the like (step S307).
[0070]
An identifier can be added to the attribute information, and the identifier can be added and stored in the external storage device 202. By using this identifier, attribute data can be associated with other data.
[0071]
The information obtained by adding information to the attribute information on the external storage device 202 can be read into the internal storage device 201 to update the attribute information.
[0072]
The operator uses the input device 205 to store, in the external storage device 202, the CAD attribute model obtained by adding the position information of the attribute arrangement plane, the display information of the attribute arrangement plane, and the attribute information to the shape model (step S308).
[0073]
Next, the “shape model and CAD attribute model” will be described.
[0074]
FIG. 4 is a diagram showing an example of the shape model, and FIG. 5 is a conceptual diagram showing the relationship between the components constituting the shape model.
[0075]
FIG. 4 shows SolidModel as a representative example of the shape model. As shown in the figure, SolidModel is an expression method for defining a shape of a part or the like in a three-dimensional space on CAD, and is composed of topology information (Topology) and geometric information (Geometry). The SolidModel phase information is hierarchically stored on the internal storage device 201 as shown in FIG.
One or more Shells,
One or more faces for one shell,
One or more Loops for one Face,
One or more Edges for one Loop,
It consists of two Vertex for one Edge.
[0076]
In addition, Surface information representing a Face shape such as a plane or a cylindrical surface with respect to the Face is stored in the internal storage device 201 in association with each other. Curve information expressing the shape of the Edge, such as a straight line or an arc, is stored in the internal storage device 201 in association with the Edge. The coordinate values in the three-dimensional space are stored in the internal storage device 201 in association with the Vertex.
[0077]
Attribute information is stored in the internal storage device 201 in association with each phase element of Shell, Face, Loop, and Vertex.
[0078]
Here, an example of a storage method on the internal storage device 201 will be described using Face information as an example.
[0079]
FIG. 6 is a conceptual diagram showing a method of storing Face information on the internal storage device 201.
[0080]
As shown in the figure, the Face information includes a FaceID, a pointer to a LoopList that constitutes the Face, a pointer to Surface data representing the Face shape, and a pointer to attribute information.
[0081]
The LoopList stores the IDs of all the Loops constituting the Face in a list format. The Surface information includes a SurfaceType and a SurfaceParameter according to the SurfaceType. The attribute information includes an attribute type and an attribute value corresponding to the attribute type. The attribute value includes a pointer to Face, a pointer to an attribute placement plane to which the attribute belongs, and the like.
[0082]
Next, with regard to “input and display of attribute information to 3D model”, in particular, it is preferable to input attribute information to 3D model, create an attribute arrangement plane, and display a 3D model to which attribute information is added. This will be described in detail based on an example.
[0083]
7 to 11 are diagrams showing a 3D model, attribute information, and an attribute arrangement plane, and FIGS. 12 to 14 are flowcharts showing processing operations when adding an attribute arrangement plane and attribute information to a 3D model. .
[0084]
In step S121 of FIG. 12, the 3D model 1 shown in FIG. 7 is created, and in step S122, a necessary attribute arrangement plane is set.
[0085]
Here, the attribute arrangement plane defines requirements relating to the display of the 3D model 1 and the attribute information added to the 3D model 1.
In the present invention, the attribute placement plane is defined by the position of one point (viewpoint, hereinafter referred to as a viewpoint) in the (virtual) three-dimensional space, the normal direction (viewing direction) of the plane to be created, and the 3D model 1, In addition, it also has information on the display magnification (hereinafter simply referred to as magnification) of the attribute information added to the 3D model 1.
[0086]
Here, the viewpoint position is defined as a position at which the 3D model 1 in the line of sight can be seen, that is, displayed. For example, the attribute arrangement plane 212 is set at a position 60 mm from the outer shape of the front face 201 of the front view of the 3D model 1 (FIG. 7).
[0087]
However, here, the projection view (front view, plan view, left and right side view, bottom view, back view) by the so-called trigonometric method may be any position as long as the viewpoint position is located outside the 3D model 1. But it has nothing to do with what is displayed.
[0088]
The position of the viewpoint is a point that coincides with the display center of the display device 204 when displaying the 3D model 1 and the attribute information added to the 3D model 1.
[0089]
Next, the direction of the normal is made to coincide with the direction of the line of sight when displaying the 3D model 1 and the attribute information added to the 3D model 1 from the viewpoint position.
[0090]
The magnification is a magnification at which a 3D model shape in a (virtual) three-dimensional space is displayed on the display device 204.
[0091]
The position of the viewpoint, the line-of-sight direction, and the magnification, which are parameters of the attribute arrangement plane, can be changed at any time.
[0092]
For example, in FIG. 7, an attribute arrangement plane 211 that is orthogonal to the plane 201a in the plan view shown in FIG. 25 and whose direction from the outside to the inside of the 3D model is the line-of-sight direction is defined. The viewpoint position and the magnification are determined in advance so that substantially all of the shape of the 3D model 1 and the attribute information to be provided can be displayed on the display screen of the display device 204 (S122 in FIG. 12). For example, in the present embodiment, the magnification is 1 and the viewpoint position 201f is set substantially at the center of the plane 201a in the plan view. (In FIG. 7, a two-dot chain line 201d indicates a state in which the approximate contour of the front view is projected on the attribute placement plane 211.) Similarly, the attribute placement plane 212 in the line of sight orthogonal to the surface 201c of the front view, and the side view of FIG. An attribute arrangement plane 213 in the line-of-sight direction orthogonal to the plane 201b is also set.
[0093]
In order to clearly indicate the position of each attribute arrangement plane, the attribute arrangement plane is represented by a rectangular double frame. The shape may be a polygon other than a rectangle, or any shape such as a circle, an ellipse, and a long circle (the attribute arrangement plane 211 is parallel to the upper surface 201a of the 3D model 1, and the attribute arrangement plane 212 is the 3D model 1 is parallel to the front surface 201b, and the attribute arrangement plane 213 has a positional relationship parallel to the side surface 201c of the 3D model 1.)
[0094]
Next, attribute information is input in association with each attribute placement plane set in step S123. 8A, FIG. 10A, and FIG. 11A are diagrams illustrating a state in which attribute information is added to the 3D model in association with the respective attribute placement planes 211, 212, and 213. 9 (b) and FIG. 11 (b) show the 3D model 1 and the attribute information as viewed from the viewpoint positions of the respective attribute arrangement planes 211, 212 and 213.
[0095]
The size of the attribute information (the height of characters and symbols) associated with the attribute placement plane is changed according to the magnification of the attribute placement plane. The size (mm) of the attribute information is defined as the size in the virtual three-dimensional space where the 3D model exists (not the size when displayed on the display device 204).
[0096]
The association between the attribute placement plane and the attribute information may be performed after the input of the attribute information. For example, as shown in the flowchart of FIG. 13, a 3D model is created (step S131), attributes are input in step S132, and attribute information is associated with a desired attribute arrangement plane in step S133. Further, if necessary, correction such as addition or deletion of attribute information associated with the attribute arrangement plane is performed.
[0097]
When the attribute information is associated with another attribute placement plane, the size of the attribute information is changed in accordance with the magnification of the destination attribute placement plane.
[0098]
The input of the attribute information may be performed in a state where the 3D model 1 is displayed two-dimensionally and displayed from the line-of-sight direction defined by each attribute arrangement plane. The input can be realized without any difference from the step of creating a two-dimensional drawing by so-called 2D-CAD. If necessary, the input may be performed while displaying three-dimensionally. Since the input can be performed while viewing the 3D model 1 three-dimensionally, the input can be realized more efficiently and without errors.
[0099]
Furthermore, a description will be given of a frame setting unit that sets a frame set so as to surround the arrangement range of the attribute information associated with the attribute arrangement plane, which is the main feature of the present invention.
[0100]
As described above, in FIG. 7, when the attribute arrangement plane corresponding to the projection view by the trigonometry is set, the rectangular frame 211a is set so as to surround the outer shape of the projected 3D model (FIG. 12). S122). Next, when the attribute information is input, if the attribute information is arranged outside the frame 211a, the size and shape of the frame 211a are set so that all the attribute information is arranged inside the frame 211a. It is changed (S124 in FIG. 12). This change is performed by detecting the coordinate position of the arranged attribute information in the three-dimensional space and automatically changing the frame 211a outside the coordinate position with the viewpoint position of the attribute arrangement plane as the center. Is what is done. In this case, it goes without saying that the change is made by the CPU device or the like. Alternatively, the operator may manually change the attribute information so that all the attribute information is arranged in the frame 211a.
[0101]
Next, a case where the attribute information of the 3D model 1 is viewed will be described. By selecting a desired attribute placement plane in step S141 of FIG. 14, the shape of the 3D model 1 is assigned in association with the attribute placement plane based on the attribute position plane viewpoint position, line-of-sight direction, and magnification selected in step S142. The displayed attribute information is displayed. For example, when the attribute placement plane 211, the attribute placement plane 212, or the attribute placement plane 213 is selected, FIG. 9 or FIG. 10A or FIG. 11B is displayed, respectively. At this time, the attribute information is arranged facing the line of sight of each attribute arrangement plane. Further, all the attribute information associated with each attribute arrangement plane is arranged in each frame. This makes it very easy and easy to see two-dimensionally on the display screen. Further, as described later, when an engineer or the like other than the operator who inputs the attribute information views the attribute information, it is only necessary to view only the inside of each frame. This means that when an extremely large three-dimensional space is set on the 3D-CAD as compared with the 3D model, the work of checking whether the attribute information is out of the frame is completely unnecessary, and efficient work is possible. It is possible.
[0102]
Next, an example will be described in which an attribute arrangement plane can be easily selected. First, a method is conceivable in which a frame of an attribute arrangement plane of a selectable 3D model is displayed, and the operator selects an attribute arrangement plane using an input device such as a pointing device such as a mouse (FIG. 7).
[0103]
Next, a method of displaying the names of selectable attribute arrangement planes in a list format and selecting from them is also conceivable (not shown).
[0104]
Furthermore, a method of selecting an image in a state viewed from the line of sight of the attribute arrangement plane (FIG. 9 or FIG. 10A or FIG. 11B) as a thumbnail image by icon display is also conceivable. (FIG. 27).
[0105]
Next, “another input method of attribute information” will be described.
[0106]
In the above-described input of the attribute information described with reference to FIGS. 11 to 14, the attribute information is associated with each attribute placement plane, but the associating means is not limited to the above. For example, the attribute information is grouped, The group may be associated with the attribute arrangement plane.
[0107]
This will be described with reference to the flowcharts shown in FIGS.
[0108]
The same results and effects as described above can be obtained by selectively grouping the attribute information input in advance or based on the search result and associating the group with an arbitrary attribute arrangement plane. Further, by making a correction such as adding or deleting the attribute information to the group, the attribute information associated with the attribute placement plane can be operated.
[0109]
That is, a 3D model is generated (step S151), attribute information is input (step S152), and the viewpoint position, line-of-sight direction, and magnification of the attribute arrangement plane are set for the 3D model (step S153). Then, the attribute information input in step S152 is grouped, and the set attribute arrangement plane is set in association with the grouped attribute information (step S154).
[0110]
When performing display, as shown in FIG. 16, an attribute placement plane is selected (step S161), and the attribute information associated with the selected attribute placement plane is changed to the viewpoint position, line-of-sight direction, The information is displayed on the display device 204 according to the magnification information (step S162).
[0111]
Next, "setting of a plurality of attribute arrangement planes" will be described.
[0112]
A case in which a plurality of attribute placement planes are set for the same viewing direction will be described (the plurality of attribute placement planes are parallel to each other).
[0113]
FIG. 17 is a flowchart showing a processing operation when a plurality of attribute arrangement planes are set for the same line of sight. FIG. 18A shows a plurality of attribute arrangement planes for the same line of sight. FIG. 6 is a diagram showing a 3D model when setting is performed.
[0114]
In the 3D model 1 shown in FIG. 7, a case will be described where a plurality of attribute arrangement planes are set such that the projection direction of the front view and the line of sight coincide.
[0115]
As described above, the 3D model 1 is created (step S171), and in step S172, an attribute arrangement plane 212 (viewpoint position, line-of-sight direction, magnification), which is the first attribute arrangement plane, is set. The line of sight of the attribute arrangement plane 212 is orthogonal to the plane 201b of the front view, the magnification is, for example, 1 ×, the viewpoint position is a position 30 mm from the outer shape of the front view, and is substantially at the center of the surface 201b of the front view.
[0116]
Then, in step S173, the attribute information as shown in FIG. 10A is input in association with the attribute arrangement plane 212, and as viewed from the line of sight of the attribute arrangement plane 212, as shown in FIG. In addition, it can be seen very easily and clearly in two dimensions.
[0117]
Next, in step 174, an attribute arrangement plane 214 (viewpoint position, line-of-sight direction, magnification), which is a second attribute arrangement plane, is set. The direction of the line of sight of the attribute placement plane 214 is parallel to the plane 201b of the front view, the magnification is, for example, 1 ×, and the viewpoint position is set to include the central axis of the hole of the attribute placement plane 3D model.
[0118]
Note that the attribute arrangement plane 214 is represented by a square painted shape.
[0119]
At this time, the 3D model 1 viewed from the attribute arrangement plane 214 has a cross-sectional shape of the 3D model 1 cut by the virtual plane 214 as shown in FIG.
[0120]
Attribute information (for example, the hole size 12 ± 0.1 in FIG. 19B) is input in association with the attribute arrangement plane 214. When the attribute placement plane 214 is selected, the sectional shape of the 3D model 1 and the attribute information associated with the attribute placement plane are displayed (FIG. 19B).
[0121]
Also in this case, the attribute information is arranged in the frame 214a of the attribute arrangement plane 214.
[0122]
Further, if the 3D model 1 is moved or rotated, a three-dimensional display can be performed as shown in FIG.
[0123]
That is, when the attribute placement plane 214 is selected, the 3D model existing in the line-of-sight direction of the attribute placement plane 214 and the attribute information associated with the attribute placement plane existing in the same line-of-sight direction area are displayed, and the opposite line-of-sight direction (FIG. (B)) The 3D model shape and attribute information of the area are not displayed.
[0124]
According to the present embodiment, it is possible to handle not only the attribute information on the outer shape but also the attribute information on the cross-sectional shape in the same line of sight direction. As a result, the attribute information can be input and displayed while looking at the cross-sectional shape, so that the point indicated by the attribute information can be easily and immediately understood.
[0125]
Further, a configuration having a plurality of attribute arrangement planes in which the shape of the 3D model 1 looks the same may be adopted. FIG. 20 shows an attribute arrangement plane 215 and an attribute arrangement plane 216 having the same viewing direction. In this example, the attribute placement plane 215 and the attribute placement plane 216 face the plan view of the 3D model 1. For example, by associating the attribute information with each of the attribute arrangement planes in a group, the attribute information can be more easily viewed. For example, FIG. 21 is a plan view of the 3D model 1 in which attribute information relating to external dimensions is grouped. FIG. 22 groups the attribute information relating to the hole position and the hole shape in the above. The grouped attribute information is associated with the attribute arrangement plane 215 and the attribute arrangement plane 216, respectively. By grouping the related attribute information in this way and assigning it to the attribute placement plane, the related attribute information can be more easily viewed.
[0126]
Next, “position of attribute information” will be described.
[0127]
In order to express the 3D model and the attribute information to be added to the 3D model on a display screen in a very easy-to-understand manner as a two-dimensional drawing, the operator appropriately selects or groups a plurality of pieces of attribute information of the part of the 3D model to be expressed and arranges the attributes. Associate with plane. In the case of a two-dimensional drawing representation method, the position of the attribute information may be arranged in the area in the line-of-sight direction of the related attribute arrangement plane. In order to make full use of the merits of the 3D model, a device is required.
[0128]
One of the merits of the 3D model is that since it can be three-dimensionally represented on the display screen in a form close to the real thing, the operator who creates the model or the operator of the next process using the model (process designer, mold designer / manufacturer) , A measurer, etc.) can save the conversion work from two-dimensional to three-dimensional (which is mainly performed in the mind of the operator), which is necessary when handling a two-dimensional diagram. This conversion work largely depends on the ability of the operator, and in this conversion work, erroneous conversion due to erroneous conversion and loss of conversion time may occur.
[0129]
In the 3D drawing, it is necessary to devise the display of the attribute information (position of the attribute information) at the time of the three-dimensional display so as not to impair the merit of the 3D model, that is, the three-dimensional model.
[0130]
The devised point will be described with reference to FIG.
[0131]
28A is a perspective view of the 3D model 2 used for description, FIG. 28B is a plan view of the 3D model 2, and FIG. 28C is a diagram in which attribute information is added to the 3D model 2 without devising it. FIG. 28 (d) is a perspective view illustrating a state in which attribute information is arranged, and the arrangement of attribute information is devised.
[0132]
First, for the 3D model 2, an attribute arrangement plane 218 is created and attribute information is input to create a two-dimensional plan view. FIG. 28B shows a state in which the image is displayed from the viewpoint of the attribute arrangement plane 218.
[0133]
Regarding the input of the attribute information, if the arrangement surfaces of the plurality of attribute information are alternately arranged as shown in FIG. 28C, the attribute information overlaps, and it becomes difficult to determine the content of the attribute information. As shown in FIG. 28 (c), even if the attribute information is small, it is difficult to see. Therefore, it can be easily imagined that if the shape is more complicated, the attribute information is no longer useful information, and the drawing cannot be realized in a perspective state.
[0134]
However, by arranging the attribute information in the same plane as shown in FIG. 28D, the attribute information does not overlap each other, and the attribute information is equivalent to the two-dimensional drawing representation (FIG. 28B). Information can be easily determined.
[0135]
In this way, in the drawing form (three-dimensional drawing) in which the attribute information is added to the 3D model, not only the representation of the two-dimensional drawing, but also the three-dimensional model, which is an advantage of the 3D model, while the attribute information is expressed three-dimensionally Can be easily determined, and can be used as a three-dimensional drawing (3D drawing).
[0136]
It is desirable that the arrangement plane of the attribute information be the same plane as the attribute arrangement plane.
[0137]
In this example, the 3D model has a simple shape. However, when handling a 3D model having an actual more complicated shape, it is necessary to set a plurality of attribute placement planes in the same line of sight.
[0138]
Then, it is conceivable that a plurality of attribute placement planes and attribute information associated therewith are simultaneously displayed, and then a desired attribute placement plane is selected or attribute information is selected.
[0139]
At this time, if the arrangement plane of the attribute information and the position of the attribute arrangement plane are far apart, it becomes difficult to understand the relationship between the attribute information and the attribute arrangement plane. To avoid this, it is preferable to arrange the attribute information on the same plane as the attribute arrangement plane in order to make the association visually easy to understand.
[0140]
Furthermore, when creating the attribute placement planes in the same line of sight described with reference to FIG. 20, it is preferable that a plurality of attribute placement planes in the same line of sight are spaced apart. When displaying a plurality of attribute placement planes and the attribute information associated therewith at the same time, if the attribute placement plane is created on the same plane, the placement plane of the attribute information will also be on the same plane. Even when viewed from an oblique direction, the pieces of attribute information overlap each other, making it difficult to see. In the first place, since there is much attribute information when viewed from the same direction, it is divided into a plurality of attribute arrangement planes, and when displaying the attribute information at the same time, it is inevitable that the attribute information overlaps.
[0141]
Even if it is not rescue that it is difficult to see from the line of sight, it is effective to arrange the attribute arrangement planes in the same line of sight apart as a means to make it easier to distinguish the attribute information in a perspective state.
[0142]
Next, the “magnification” will be described.
[0143]
Further, by setting the magnification of the attribute arrangement plane to a desired magnification, a complicated shape or a detailed shape can be more easily seen.
[0144]
FIG. 23 is a diagram illustrating a state in which a part of the 3D model 1 is enlarged and displayed. For example, as shown in FIG. 23 (a), by setting the attribute arrangement plane 217 in which the line of sight is directed to the plan view, the viewpoint position is near the corner, and the magnification is, for example, 5 times, for the 3D model 1, The step-like shape and attribute information can be displayed in an extremely easy-to-understand manner (FIG. 23B). Also in this case, the attribute information associated with the attribute arrangement plane 217 is all arranged in the frame 217a. The attribute placement plane 217 is equivalent to a so-called local projection view. However, by viewing only the inside of the frame 217a, all the associated attribute information can be viewed, and the attribute to the 3D model outside the frame 217a can be viewed. Since there is no need to confirm the presence or absence of information at all, efficient work can be realized.
[0145]
Further, information of the attribute arrangement plane to be associated is displayed in the frame of the attribute arrangement plane to be associated.
[0146]
In the present embodiment, the present invention is effective for 3D-CAD in general and 2D-CAD irrespective of the hardware configuring the 3D-CAD apparatus or the method of configuring the 3D shape model.
[0147]
Next, “magnification and size of attribute information” will be described.
[0148]
The size of the attribute information (the height of a character or a symbol) associated with the attribute placement plane is changed according to the magnification of the attribute placement plane. FIG. 23 (b).
The size (mm) of the attribute information is defined as the size in the virtual three-dimensional space where the 3D model exists (not the size when displayed on the display device 204).
[0149]
For example, the size of the attribute information is 3 mm on the attribute arrangement plane 211 (magnification 1). FIG. 23C shows an example in which the character height is similarly displayed as 3 mm on the attribute arrangement plane 217 (magnification 5).
[0150]
Since the attribute information associated with the attribute arrangement plane 217 is displayed at a display magnification of 5 times, its size is 15 mm.
[0151]
In (b) and (c) of FIG. 23, a square line indicates a displayable range on the display device 204.
[0152]
If the attribute information is arranged so as not to overlap, the position of the attribute information is separated from the 3D model, so that it is difficult to understand the relationship between the shape and the attribute information related thereto, and there is a possibility of misreading. Also, if there is much attribute information to be displayed, all the attribute information cannot be displayed on the display device 204, and the display range must be changed to see the attribute information outside the displayable range.
[0153]
If the size of the character is not changed when displaying in a reduced size (the magnification is less than 1), the display size of the attribute information on the display device 204 is reduced in the reduced view display state, and the content of the attribute information is determined. become unable.
[0154]
Therefore, it is desirable to change the size of the attribute information according to the size magnification in consideration of the time when the attribute information is displayed.
[0155]
For this reason, it is preferable that the magnification and the size of the attribute information be approximately inversely proportional. As an example, when the magnification of the attribute placement plane 211 is 1 and the size of the attribute information is 3, the size of the attribute information associated with the attribute placement plane 217 is 0.6 mm.
[0156]
Next, “selection of a plurality of attribute placement planes” will be described.
[0157]
In the above embodiment, when displaying the attribute information associated with the attribute placement plane, the number of the attribute placement planes to be selected is only one. However, in view of the object of the present invention, a plurality of attribute placement planes are displayed. There is no problem with choosing.
[0158]
However, when performing a single selection of the attribute arrangement plane, there is only one viewpoint position and line-of-sight direction, so there is only one display method on the display device. So you have to be creative. For example, when multiple selections are made, all the attribute information associated with the selected attribute placement plane is displayed, and it is possible to select which attribute placement plane setting to use for the viewpoint position and gaze direction. Can be considered.
[0159]
In addition, the display of the attribute information is devised so that the group can be easily identified by changing the color for each related attribute arrangement plane.
[0160]
Next, "setting of the horizontal or vertical direction of the attribute arrangement plane" will be described.
[0161]
In the present invention, only the position of the viewpoint, the line of sight direction, and the magnification are set on the attribute arrangement plane, and the setting of the horizontal or vertical direction of the attribute arrangement plane is not mentioned.
[0162]
In the two-dimensional drawing, as shown in FIG. 25, a rule is provided for the arrangement of a view (a plan view, a front view, and a side view) viewed from each line of sight. This is a device for expressing the three-dimensional shape of the real object on a two-dimensional plane so that the positional relationship from each line-of-sight direction can be easily understood.
[0163]
On the other hand, in a 3D drawing form in which attribute information is added to a 3D model to make a drawing, a two-dimensional representation viewed from a direction orthogonal to the outer surface of the 3D model (FIGS. 9 and 10B, FIG. 11). In addition to (b)), the 3D model is rotated from this state, and a three-dimensional expression ((a) in FIG. 10 and (a) in FIG. 11) viewed from an oblique direction is also possible.
[0164]
Therefore, in the form of the 3D drawing, when displaying the plan view, the front view, and the side view, the horizontal direction or the vertical direction of the attribute arrangement plane (this horizontal direction or the vertical direction is assumed to correspond to each direction of the display screen). ) Does not need to be specified separately. If the 3D model and the attribute information assigned to the 3D model can be correctly expressed, it can be said that all of (a), (b), (c), (d), and (e) shown in FIG. 29 are correct expressions. . Furthermore, if the 3D model is slightly rotated, the 3D model can be three-dimensionally expressed, and the position of the part that has been viewed at the present time corresponds to the entire 3D model, and the location of the plan view and the side view viewed from another viewing direction can be easily determined. This is because there is no particular problem even if the display is performed without concern for the positional relationship between the viewing directions in the horizontal direction or the vertical direction of the attribute arrangement plane.
[0165]
However, in a 3D drawing form in which attribute information is added to the 3D model, not all operators who handle the 3D drawing have an environment in which the 3D model can be freely rotated and displayed. This is because there is a workplace where it is sufficient to save and view the two-dimensional image information electronic data format displayed by each attribute arrangement plane without modifying the 3D drawing and view it. There are also workplaces that cannot be handled without them.
[0166]
Assuming such a situation, it is necessary to apply a rule such as a two-dimensional drawing for the display viewed from each line of sight.
[0167]
Therefore, when creating the attribute placement plane, it is necessary to set the horizontal direction or the vertical direction when displayed on the display device 204.
[0168]
FIG. 30 shows a flowchart of the processing.
[0169]
First, a 3D model is created (step S301).
[0170]
Next, the position of the viewpoint, the viewing direction, and the magnification are set for the 3D model, and an attribute arrangement plane is created (step S302).
[0171]
Then, the horizontal direction (or the vertical direction) of the attribute arrangement plane is designated. (Step S303) In order to specify the horizontal direction (or the vertical direction), the directions (X, Y, Z) of three axes existing in the (virtual) 3D space may be selected. The direction of the ridge line or the vertical direction of the surface may be selected.
[0172]
By specifying the horizontal direction (or the vertical direction) of the attribute arrangement plane, the display position of the 3D model and the attribute information displayed by selecting the attribute arrangement plane is uniquely determined.
[0173]
When creating another attribute placement plane, the horizontal direction (or the vertical direction) may be specified while observing the relationship with the line-of-sight direction of the already created attribute placement plane.
[0174]
Next, “display method of attribute information” will be described.
[0175]
In the above embodiment, as an order for selectively displaying the attribute information input to the 3D model, first, an attribute arrangement plane is selected, and then the attribute information associated with the attribute arrangement plane is appropriately displayed. The description has been made in this order. However, the present invention is not limited to this method. The attribute information is selected, and then the position of the viewpoint, the line-of-sight direction, and the magnification of the attribute arrangement plane with which the attribute information is associated are selected. However, a method of displaying the 3D model and the attribute information is also effective.
[0176]
FIG. 31 (displayed from selection of attribute information) is a flowchart showing this series of processing operations.
[0177]
While the 3D model and the attribute information of the plan view of FIG. 8 are displayed, a hole diameter φ12 ± 0.2 is selected. Step 311.
[0178]
This attribute information displays the 3D drawing and the attribute information associated with the attribute arrangement plane 211 based on the viewpoint position, the line-of-sight direction, and the magnification set in the associated attribute arrangement plane 211. Step 312. In this case, a front view is displayed as shown in FIG.
[0179]
Thereby, the relationship between the selected attribute information and the 3D model is displayed two-dimensionally, so that it is easier to recognize.
[0180]
・ Surface selection method
In the above embodiment, as an order for selectively displaying the attribute information input to the 3D model, first, an attribute arrangement plane is selected or attribute information is selected, and then the attribute arrangement plane and the attribute information are associated. The method of appropriately displaying the attribute information associated with these attribute placement planes based on the set attribute placement plane has been described. However, the present invention is not limited to this method, and it is not limited to this method, and the geometric information (Geometry) of the 3D model may be used. ) To display the attribute information associated with the geometric information, and further display the 3D model and the attribute information with the viewpoint position, line-of-sight direction, and magnification of the attribute arrangement plane associated with the attribute information. Is also effective.
[0181]
FIG. 32 (displayed from selection of attribute information) is a flowchart showing this series of processing operations.
[0182]
The geometric information (edge, face, vertex) of the 3D model is selected (step 321).
[0183]
The attribute information associated with the selected geometric information is displayed (step 322).
[0184]
If there are a plurality of associated attribute information items, all of them may be displayed. Further, all the attribute information belonging to the attribute arrangement plane with which the attribute information is associated may be displayed.
[0185]
Next, the 3D model and the attribute information are displayed based on the viewpoint position, line-of-sight direction, and magnification (horizontal direction of the attribute arrangement plane) of the attribute arrangement plane related to the displayed attribute information. At this time, when a plurality of attribute placement planes are candidates, the operator is caused to select a target to be displayed.
[0186]
As described above, related attribute information can be searched and displayed using the geometric shape of the 3D model as a key, so that it is very easy to use.
Geometric information selection → Display related attribute information (single) → Display by display position of related attribute placement plane
Select geometric information → display related attribute information (single) → display related attribute placement plane display position. Displays all attribute information associated with the attribute placement plane
Geometric information selection → related attribute information display (multiple) → display at related attribute placement plane display position (single attribute placement plane)
Select geometric information → display related attribute information (plural) → display at the display position of related attribute placement plane (single attribute placement plane). Displays all attribute information associated with the attribute placement plane
Geometric information selection → related attribute information display (multiple) → display at related attribute placement plane display position (multiple attribute placement plane)
Select geometric information → display related attribute information (plural) → display at the display position of related attribute placement plane (plural attribute placement plane). Displays all attribute information associated with the attribute placement plane
Next, the display of the 3D model to which the attribute information created as described above is added will be described.
[0187]
The 3D model to which the attribute information created by the information processing apparatus illustrated in FIG. 2 is added may be transmitted to the created apparatus itself or the data of the created 3D model via an externally connected device, and may be used in another similar manner. It can be displayed and used in each step shown in FIG. 1 by using the information processing device.
[0188]
First, a 3D model created by a product / unit / part design engineer or an operator who is a design designer himself writes the 3D model created by himself / herself into FIG. 9, FIG. 10 (b), and FIG. 11 (b). By performing the display as shown in (1), new attribute information can be added to the 3D model as if a two-dimensional drawing was created. Further, for example, when the shape is complicated, the 3D model is displayed in a three-dimensional display and a two-dimensional display alternately or as necessary on the same screen as needed, so that desired attribute information can be efficiently and accurately displayed. Can be entered.
[0189]
Further, an operator in a position of checking / approving the created 3D model displays the created 3D model on the same screen or by switching the display shown in FIGS. 9, 10 (b) and 11 (b). By doing so, a check is performed, and attribute information such as a mark, a symbol, or coloring that indicates checked, OK, NG, suspension, or requiring further study is added. Needless to say, a check is performed while comparing and referring to a plurality of products / units / parts as necessary.
[0190]
Also, a design engineer or a design designer other than the creator of the created 3D model can refer to the created 3D model and use it when designing another product / unit / part. By referring to this 3D model, the intention of the creator or the design method can be easily understood.
[0191]
Further, in producing and manufacturing a 3D model, an operator who adds information necessary for the 3D model to the 3D model or the attribute information can be used. In this case, the operator is a technician who sets the manufacturing process of the product / unit / part. The operator adds, for example, an instruction of the type of machining process, a tool to be used, or the like, or a corner R, a chamfer to a ridge, a corner, a corner, or the like necessary for machining to the 3D model. Alternatively, a measurement method instruction for dimensions, dimensional tolerances, etc., addition of measurement points to the 3D model, information to be noted in measurement, and the like are input. These can be efficiently and reliably performed while viewing the display that is arranged and created in an easy-to-view manner as shown in FIGS. 9, 10 (b) and 11 (b), and three-dimensionally confirming the shape as necessary. Done.
[0192]
Further, in producing and manufacturing a 3D model, an operator who obtains information necessary for making a desired preparation from the 3D model or the attribute information can be used. In this case, the operator is a design engineer who designs dies, jigs and tools, various devices, and the like necessary for manufacturing and manufacturing. The operator understands and grasps the shape while viewing the 3D model in a three-dimensional state, and displays necessary attribute information in an easily viewable display as shown in FIGS. 9, 10 (b) and 11 (b). Check and extract. Based on the attribute information, the operator designs dies, jigs and tools, various devices, and the like. For example, when the operator is a mold design engineer, the operator designs the mold while examining the configuration, structure, and the like of the mold from the 3D model and the attribute information. If necessary, corners R and chamfers are added to ridges, corners, corners, and the like necessary for mold production. When the mold is a resin injection mold, the operator adds, for example, a draft necessary for molding to the 3D model.
[0193]
It can also be used by operators who manufacture and manufacture products / units / parts. In this case, the operators are processing engineers and assembling engineers of products / units / parts. The operator easily understands and grasps the shape to be machined or the shape to be assembled while viewing the 3D model in a three-dimensional state, and arranges them as easily seen in FIGS. 9, 10 (b) and 11 (b). Processing and assembling are performed by looking at the created display. Then, if necessary, the operator checks the shape and the like of the processing section and the assembly section. Further, the processed, difficult to process, or the processing result may be added as attribute information to the 3D model or the already added attribute information, and the information may be fed back to a design engineer or the like.
[0194]
Also, an operator who inspects, measures, and evaluates manufactured / manufactured products / units / parts can be used. In this case, the operator is a technician who inspects, measures, and evaluates products / units / parts. The operator displays the measurement method, measurement point, and information to be noted in the measurement for the dimensions, dimensional tolerances, and the like in an easily viewable manner as shown in FIGS. 9, 10B, and 11B. Inspection, measurement, and evaluation are carried out efficiently and reliably while checking the shape and confirming the shape three-dimensionally as necessary. Then, the operator can add inspection, measurement, and evaluation as attribute information to the 3D model as needed. For example, a measurement result corresponding to the dimension is given. In addition, a mark or a symbol is added to attribute information of a defective portion such as a defect outside the dimensional tolerance or a flaw or a 3D model. In addition, similarly to the check result, an inspection, measurement, evaluated mark, symbol, coloring, or the like may be performed.
[0195]
In addition, operators in various departments and roles related to production / manufacture of products / units / parts can be used. In this case, the operator creates, for example, a person in charge of analyzing production and manufacturing costs, or a person in charge of ordering products / units / parts themselves, related various parts, etc., manuals for products / units / parts, packing materials, and the like. Person in charge, etc. Also in this case, the operator can easily understand and grasp the shapes of the products / units / parts while viewing the 3D model in a three-dimensional state, and can easily view the shapes as shown in FIGS. 9, 10B and 11B. Perform various tasks efficiently by looking at the display created and arranged.
[0196]
Next, the inspection instruction will be described.
[0197]
As described above, in order to inspect the completed molds and parts, dimensions and the like are assigned to the 3D model in advance and displayed.
[0198]
Here, the attribute information is input so that the position to be inspected is displayed clearly on the set attribute arrangement plane.
[0199]
That is, the inspection order, inspection position, inspection item, and the like are input for a surface, a line, a ridge line, and the like constituting the 3D model. By performing the inspection in that order, the number of inspection steps is reduced.
[0200]
First, by inputting an item and a position to be inspected, the whole is input. Next, the inspection order is allocated by a predetermined method, and the order is assigned to each item. When the inspection is actually performed, the attribute arrangement plane is selected by designating the order, and the surface of the position to be inspected in the displayed attribute arrangement plane has a different form (color, etc.). Are different), and the inspection position becomes clear.
[0201]
Then, for each designated inspection item, the inspection result is input, and it is determined whether or not reshaping is necessary.
[0202]
As described above, according to the embodiment of the present invention, an easy-to-view screen can be obtained by a simple operation based on the set attribute arrangement plane and attribute information. Further, the relationship between the line-of-sight direction and the attribute information can be understood in a list. Furthermore, erroneous reading due to an operation error by the operator is reduced by inputting dimension values and the like in advance.
[0203]
In addition, only the information associated with the line of sight can be viewed, and necessary information can be easily known.
[0204]
Also, by assigning a large amount of attribute information in the same line-of-sight direction to a plurality of attribute arrangement planes, an easy-to-view screen can be obtained, and necessary information can be easily known.
[0205]
In addition, by setting the attribute arrangement plane inside the 3D model, that is, the cross-sectional shape, the attribute information can be displayed in an easily understandable manner.
[0206]
In addition, since the size of the attribute information is changed according to the display magnification of the attribute arrangement plane, it can be easily understood and appropriately expressed.
[0207]
Further, by arranging the attribute information on the attribute arrangement plane, the attribute information can be read even when the 3D model is three-dimensionally viewed obliquely.
[0208]
Also, by using the attribute information as a key, it is possible to search for an attribute arrangement plane and to see only information associated with the attribute arrangement plane, and to easily know necessary information.
[0209]
Also, by using the geometric information as a key, it is possible to search for the attribute information and the attribute arrangement plane, and to see only the information associated with the attribute arrangement plane, and to easily know necessary information.
[0210]
FIG. 39 is a flowchart showing a series of flows for associating one attribute placement plane with another attribute placement plane. The attribute arrangement plane to be associated is A, and the attribute arrangement plane to associate is B. First, B is selected (step 2001). An association command is selected (step 2002). Next, A is selected (step 2003). It is confirmed by selecting YES / NO whether the attribute arrangement plane to be associated may be A (step 2004). Select YES to end.
[0211]
FIG. 46 shows that the attribute arrangement planes can be associated in a tree structure. That is, the association of the attribute arrangement planes can be hierarchically associated with a plurality of attribute arrangement planes. E-1 is an enlarged display of the tree structure, and E-2 is a display of the model and the attribute arrangement plane at that time. The tree structure can be displayed on the screen by switching between display and non-display.
[0212]
FIG. 40 is a diagram (A-2) illustrating a state when the attribute arrangement plane a-1 is directly displayed, which is created for viewing the cross-sectional view of the model. In order to see the local area in the cross section, the attribute allocation plane (a-2) of the local diagram is associated with the attribute allocation plane (a-1). At this time, the attribute information is stored in a setting for each attribute arrangement plane. When a-1 is directly displayed, the frame of a-2 and the name of a-2 are displayed. This name may be displayed in the frame, drawn as a note, or displayed near the frame. Then, the setting does not automatically change to one of the settings.
[0213]
FIG. 41 shows a state in which one attribute arrangement plane is associated with a parent and another attribute arrangement plane is associated with a child. B-2 represents the entire model. The attribute arrangement plane to be associated is b-1. Assume that the attribute arrangement planes to be associated are b-2, b-3, and b-4. At this time, when the attribute arrangement plane b-1 as the parent is directly displayed, the associated attribute arrangement planes b-2, b-3, and b-4 are displayed as cutting lines like B-1. You. At this time, the name is also displayed, and it is desirable to display the name with a cutting symbol as shown in FIG. The frame of the attribute arrangement plane b-1 is arranged so as to include the attribute arrangement planes b-2, b-3, and b-4.
[0214]
In the present invention, the display setting means is provided so that the setting (size, color, etc.) of the attribute information associated with the attribute arrangement plane can be set for each attribute arrangement plane. This means may be configured to be saved with the same settings without being changed by association, but the following configuration may be used.
[0215]
FIG. 42 shows that, when an arbitrary attribute arrangement plane f-1 is associated with another attribute arrangement plane f-2, the attributes of the attribute information of the associated attribute arrangement plane f-1 are simultaneously associated with the attribute arrangement plane f 6 is a flowchart illustrating a series of flows in which a setting is changed to an attribute of attribute information of -2. First, the attribute arrangement plane f-1 is selected (step 4001). Next, the attribute placement plane f-2 is selected (Step 4002), and the attribute placement plane f-1 is associated (Step 4003). At the same time as the association, the setting of the attribute information of the attribute arrangement plane f-1 is changed to the setting of the attribute information of the attribute arrangement plane f-2 (step 4004). The setting of the attribute information after the change is stored by the storage means and displayed by the display means (step 4005).
[0216]
With this function, you can first create (parent) attribute placement planes, create multiple (child) attribute placement planes, and then unify the attributes of attribute information collectively, saving time and effort. be able to.
[0219]
FIG. 43 shows a display state when a certain attribute arrangement plane g-1 is associated with other attribute arrangement planes g-2 and g-3. As shown in the figure, information on the associated attribute arrangement planes g-2 and g-3 is displayed in the frame of the associated attribute arrangement plane g-1. When this information is displayed, it is possible to know how many (child) attribute placement planes are associated with the (parent) attribute placement plane, so that there is no need to overlook the (child) attribute placement plane.
[0218]
FIG. 44 is a diagram showing that each attribute placement plane is associated with another attribute placement plane regardless of the direction, regardless of the orientation. Here, the associated (parent) attribute arrangement plane is c-1 and the associated (child) attribute arrangement plane is c-3, which is equivalent to an enlarged part view. By making this association, an arrow view is not required. That is, it is generally necessary to set an attribute arrangement plane corresponding to an arrow view having a normal direction perpendicular to the slope, and then associate c-3 with the attribute arrangement plane. By associating c-3, an attribute arrangement plane corresponding to the above-mentioned arrow view becomes unnecessary.
[0219]
(Second embodiment)
In the above-described embodiment, the frame setting means for setting a frame set so as to surround the arrangement range of the attribute information associated with the attribute arrangement plane has been described. First frame setting means for setting a first frame set so as to surround the arrangement range of the attribute information, and second frame setting for setting a second frame indicating the existence of the attribute arrangement plane It can also be realized by means. This will be described below.
[0220]
FIG. 33 shows a simple 3D model 1001 for explanation. The 3D model 1001 has a rectangular parallelepiped shape, and has a hole 1001a which is very small compared to the outer shape on one surface. As can be seen from FIG. 33, the shape of the hole 1001a is extremely difficult to determine when the entire outer shape can be seen. The situation as shown in FIG. 33 is not special, but occurs very frequently in so-called exterior parts, cases or chassis of industrial products having relatively large shapes. That is, in the above-mentioned parts, even if the appearance part does not have a fine shape, the shape part having the function of the inside part, or the attachment part with other parts, etc., has a shape part smaller than the whole outer part. is there.
[0221]
In such a case, it is necessary to notify the operator of the existence of the shape portion to which the attribute information such as the dimension is added, and the second indicating the existence of the attribute arrangement plane with which the added attribute information is associated. A frame is displayed. The second frame is typically preferably rectangular, but is not limited to this, and may be any shape that can indicate the existence of an attribute arrangement plane, such as a polygon, a circle, an ellipse, or an oval. , Any shape. The setting of the second frame is performed by specifying two points on the diagonal of the rectangle, specifying the center point of the rectangle and inputting the width and height, inputting the center and radius of the circle, and so on. It is done in a well-known way to indicate and enter. Needless to say, the setting and display of the second frame are performed by the CPU device, the internal storage device, the input device, and the display device.
[0222]
FIG. 34 shows a typical situation of the second frame. A second frame 1002 indicating the presence of an attribute placement plane corresponding to the plan view of the 3D model 1001, a second frame 1003 indicating the presence of an attribute placement plane corresponding to the front view, and a sectional view of the hole 1001a. A second frame 1004 indicating the presence of the attribute placement plane is displayed.
[0223]
Necessary attribute information is associated with each attribute arrangement plane. The attribute arrangement plane corresponding to the cross-sectional view of the hole 1001a having the frame 1004 is associated with four dimensions shown in FIG. In this case, as shown in FIG. 35, the size of the attribute information is set such that when the hole portion 1001a is displayed on the monitor screen 1006 at an appropriate easy-to-see display magnification, the size becomes appropriate and easy to see. Conversely, if such attribute information is displayed as shown in FIG. 33, it cannot be determined at all. When the 3D model has a complicated shape, it is difficult to determine the presence or absence of the attribute information of the fine shape portion. However, the presence of the attribute information can be quickly known by the second frame, and the efficiency is high. Various operations can be performed.
[0224]
Further, in the present embodiment, a first frame for notifying the arrangement range of the attribute information associated with the attribute arrangement plane can be set. In FIG. 35, a first frame 1005 is set on the attribute placement plane so as to include the shape of the hole 1001a and four dimensions. The shape, setting, and display of the first frame 1005 are the same as those of the second frame.
[0225]
Since all the attribute information associated with the attribute arrangement plane is arranged inside the first frame 1005, the operator need only look at the attribute information or the shape inside the first frame 1005. This means that if it is necessary to view a small shape portion as shown in FIG. 35 at an increased display magnification, and if there is no first frame 1005 that informs the arrangement range of the attribute information, the operator Means that the presence or absence of attribute information has to be checked for the entire 3D model corresponding to the cross-sectional view cut by the virtual plane having the second frame 1004. This means that it is necessary to look at the entire cross section where only the hole 1001a in the cross sectional view should be seen, which significantly impairs the work efficiency. Further, if there is no second frame 1004 indicating the existence of the attribute arrangement plane with which the attribute information is associated, the operator needs to find the first frame 1005 smaller than the second frame 1004, and This impairs the efficiency. Further, when the 3D model has a complicated shape, the first frame 1005 cannot be searched for, or the first frame 1005 is not noticed, and a remarkable trouble may occur in various operations.
[0226]
According to the present embodiment, the existence of the attribute arrangement plane can be easily known in the second frame, and necessary information can be very easily diagnosed in the required range in the first frame, thereby realizing an extremely efficient operation. You can do it.
[0227]
Further, in order to clearly indicate the position of the first frame with respect to the second frame of the present embodiment, for example, a process as shown in FIG. 36 may be performed. In FIG. 36, the position of the first frame 1005 is clearly indicated with respect to the second frame 1004 by connecting the four vertices of the second frame 1004 and the corresponding four vertices of the first frame 1005 with lines. can do. By clearly indicating the position of the first frame 1005, the first frame 1005 can be selected more easily, and more efficient work can be performed.
[0228]
In the above description, in the case where the second frames 1002 and 1003 surround the entire outer shape similarly to the frames 211a, 212a and 213a in FIGS. , 1003 may be omitted, and the frames 1002, 1003 may be configured to serve as the first frame and the second frame.
[0229]
FIG. 37 shows a flowchart for the above contents. After creating the 3D model in S1001, an attribute arrangement plane is set in S1002, and a second frame for notifying the existence of the attribute arrangement plane is set. In step S1003, a first frame for notifying the arrangement range of the attribute information is set as necessary. If the first frame is not required, the second frame also serves as the first frame. Thereafter, in S1004, the attribute information is input in association with the attribute arrangement plane. In S1005, if the attribute information is arranged outside the range of the first frame or the first and second frames, the first The size of the frame or the first and second frames is changed.
[0230]
In the present embodiment, first frame setting means for setting a first frame set to surround the arrangement range of the attribute information associated with the attribute arrangement plane, and the presence of the attribute arrangement plane is notified. With the second frame setting means for setting the second frame, the attribute information added to the 3D model can be easily and easily displayed and efficiently displayed.
[0231]
(Other embodiments)
Other embodiments will be described for the setting of the first frame set so as to surround the arrangement range of the attribute information associated with the attribute arrangement plane and the setting of the second frame indicating the existence of the attribute arrangement plane.
[0232]
As described in the second embodiment, the present invention is limited only when the second frame also serves as the first frame, or only when the first frame is set as a part of the second frame. Rather, the relative size (size) or positional relationship between the first frame and the second frame is set so that the first frame surrounds the arrangement range of the attribute information associated with the attribute arrangement plane. The present invention can be applied to any configuration as long as the second frame can achieve the purpose of notifying the existence of the attribute arrangement plane.
[0233]
For example, as shown in FIG. 38, the second frames 1013 and 1014 in the same line-of-sight direction on the attribute arrangement plane are arranged in the same shape in the same line-of-sight direction with a size smaller than the shape of the 3D model. You may. In this case, the first frame 1011 is larger than the second frame 1013, or the positions of the first frame 1012 and the second frame 1014 on the attribute arrangement plane are different. In this case, when performing two-dimensional display as described in the first embodiment, the display center is the center of the first frames 1011 and 1012.
[0234]
The association between the first frame and the second frame is not limited to connecting each corresponding vertex of the second embodiment with a line, and the first frame and the second frame are associated with each other. The method is not limited as long as the operator can understand what the user is doing. For example, the first frame and the second frame may have different shapes or line types, and the first frame and the second frame of the same color may be associated with each other.
[0235]
It is preferable that the display and non-display of the first frame and the second frame can be set independently. For example, the operator displays only the second frame, finds a desired frame, displays the first frame, displays the first frame two-dimensionally based on the first frame, and looks at the attribute information. At this time, the second frame is unnecessary and may be hidden.
[0236]
