In step S104, step S1
The mold manufacturing process is examined based on the mold drawing created in 03, and a mold process drawing is created. The die processing step includes NC processing and general-purpose processing. For the step 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.

In step S105, an NC program is created based on the mold drawing.

In step S106, a mold part is manufactured (processed) using a machine tool or the like.

In step S110, step S1
Based on the result of the inspection in step 09, the mold at the place where the accuracy of the molded product is insufficient is corrected (corrected).

(Product Design) Next, a product is designed.
Creation of a design drawing of each component will be described. The design drawing of the part is created by a 2D-CAD device or a 3D-CAD device.

Here, the design of parts will be described using the information processing apparatus shown in FIG. 2, for example, a CAD apparatus.

FIG. 2 is a block diagram of the CAD apparatus.
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.

Reference numeral 203 denotes a CPU device which controls each block in the figure and executes processing in accordance with the instructions of the CAD program.

Reference numeral 204 denotes a display device, and the CPU device 20
A two-dimensional or three-dimensional shape or the like is displayed according to the instruction of No. 3.

Reference numeral 205 denotes an input device such as a mouse, a keyboard, and a tablet for giving an instruction to a CAD program or the like.

Reference numeral 206 denotes an output device such as a printer for outputting a paper drawing or the like in accordance with an instruction from the CPU device 203.

Reference numeral 207 denotes an external connection device.
The AD device is connected to an external device to supply data from the device to the external device or to control the device from the external device.

FIG. 3 is a flowchart showing the processing operation of the CAD apparatus shown in FIG.

First, when the operator instructs the start 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).

When an 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 using the input device 205, the external storage device 2
02 can be read into the internal storage device 201 so that it can be handled on a CAD program.

The operator creates an attribute placement plane, which is a virtual plane, in the three-dimensional space in which the shape model has been created using the input device 205 (step S303).

In order to make it easy to determine the position of the attribute arrangement plane, it is displayed on the display device as image information such as a frame (double frame, filling in the frame). The setting information of the attribute arrangement plane is associated with the shape model and stored in the internal storage device 2.
01.

It is desirable to give a name to the attribute arrangement plane created as needed.

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.

The operator associates the attribute information with the attribute arrangement plane using the input device 205. (Step S
305) The attribute information and the information related to the attribute arrangement plane are stored in the internal storage device 2.
01. The operator may designate an attribute arrangement plane in advance and perform attribute assignment while associating the attribute arrangement plane with the attribute arrangement 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.

Next, the operator designates an attribute placement plane by using the input device 205 to display / hide an attribute placement plane and attribute information such as a dimensional tolerance associated with the attribute placement plane, or perform coloring or the like. Display control is performed (step S306).

Further, when the operator creates an attribute placement plane using the input device 205, the operator sets the viewpoint position, line-of-sight direction, and magnification of the attribute placement plane. By setting the attribute arrangement plane display information and designating the attribute arrangement plane, the shape model can be displayed with the set viewpoint position, line-of-sight direction, and magnification. 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.

According to the instruction of the operator, the attribute information can be stored in the external storage device 202 or the like (step S307).

An identifier can be added to the attribute information,
This identifier can be added and stored in the external storage device 202. Using this identifier, attribute data can be associated with other data.

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.

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).

Here, the shape model and the CAD attribute model will be described.

meter. 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.

(Input and Display of Attribute Information to 3D Model)
Further, input of attribute information to the 3D model, a method of creating an attribute arrangement plane, and display of the 3D model to which the attribute information is added will be described in detail.

FIGS. 7 to 11 are diagrams showing the 3D model, the attribute information, and the attribute arrangement plane. FIGS. 12 to 14 show the processing operation when the attribute arrangement plane and the attribute information are added to the 3D model. It is a flowchart.

In step S121 in FIG. 12, the 3D model 1 shown in FIG. 7 is created, and in step S122, a necessary attribute arrangement plane is set.

(Attribute arranging plane) Here, the attribute arranging plane defines items related 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 (hereinafter referred to as a viewpoint) in a (virtual) three-dimensional space, the normal direction (viewing direction) of the plane to be created, and the 3D model 1, and information on the display magnification (hereinafter simply referred to as magnification) of the attribute information added to the 3D model 1.

Here, the line-of-sight position defines a position at which the 3D model 1 in the line-of-sight direction 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 in the front view of the 3D model 1 (FIG. 7).

Here, regarding the projections by the so-called trigonometric method (front view, plan view, left and right side views, bottom view, back view), if the line of sight is located outside the 3D model 1, In any position, it has nothing to do with the displayed content.

The position of the viewpoint corresponds to the display center of the display device 204 when the 3D model 1 and the attribute information added to the 3D model 1 are displayed.

Next, the direction of the normal line 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.

The magnification refers to a magnification at which a 3D model shape in a (virtual) three-dimensional space is displayed on the display device 204.

The position of the viewpoint, the direction of the line of sight, and the magnification, which are parameters of the attribute arrangement plane, can be changed at any time.

For example, in FIG. 7, the attribute placement plane 2 is orthogonal to the plane 201a in the plan view shown in FIG. 25 and the direction from the outside to the inside of the 3D model is the line of sight.
11 is defined. The viewpoint position and the magnification are determined so that substantially the entire 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. 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 shows 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.
An attribute arrangement plane 213 in the viewing direction orthogonal to the surface 201b in the side view is also set.

In order to specify the position of each attribute arrangement plane,
The attribute arrangement plane is represented by a double square frame. In addition,
The inside of the frame is colored, making it easy to identify each attribute arrangement plane. In the present embodiment, a frame is used as a means for clearly indicating the position of the attribute arrangement plane. However, the present invention is not limited to this. The shape may be a polygon other than a square or a circle. (Attribute placement plane 21
1 is parallel to the upper surface 201a of the 3D model 1, the attribute placement plane 212 is parallel to the front face 201b of the 3D model 1, and the attribute placement plane 213 is the side face 201c of the 3D model 1.
And a parallel positional relationship. )

Next, attribute information is input in association with each attribute placement plane set in step S123. FIG.
FIGS. 10A and 11A are diagrams showing a state in which attribute information is added to the 3D model in association with each of the attribute arrangement planes 211, 212, and 213. 9 (b) and FIG. 11 (b) show respective attribute arrangement planes 211,
3D model 1 and attribute information viewed from the viewpoint positions 212 and 213.

The size of the attribute information (the height of characters and symbols) associated with the attribute arrangement plane is changed according to the magnification of the attribute arrangement plane. The size (mm) of the attribute information is 3
It is defined as the size in the virtual three-dimensional space where the D model exists. (It is not the size when displayed on the display device 204.) Further, the association between the attribute arrangement 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 S13).
1) After inputting the attributes in step S132, step S132
At 133, attribute information is associated with a desired attribute arrangement plane. Further, if necessary, correction such as addition or deletion of attribute information associated with the attribute arrangement plane is performed.

When the attribute information is associated with another attribute placement plane, the size of the attribute information is changed according to the magnification of the destination attribute placement plane.

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 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 the image 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.

Next, the 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 in 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. This makes it very easy and easy to see two-dimensionally on the display screen.

Next, an example will be described in which an attribute arrangement plane and a group constituted by the attribute arrangement plane can be easily selected.

First, a frame of a selectable 3D model attribute arrangement plane is displayed, and an operator selects an attribute arrangement plane or a group of attribute arrangement planes using an input device such as a pointing device such as a mouse. (FIG. 7).

Next, a method is conceivable in which names of selectable attribute arrangement planes and groups of attribute arrangement planes are displayed in the form of a list, and are selected from the list (not shown).

Further, the state viewed from the line of sight of the attribute arrangement plane (FIG. 9 or FIG. 10A, or FIG.
A method of selecting and displaying the image of (1) (b) as an icon as a thumbnail image is also conceivable (FIG. 27).

(Other Input Method of Attribute Information) In the input of the attribute information described above with reference to FIGS. 11 to 14, the attribute information is associated with each attribute arrangement plane, but the associating means is limited to the above. Instead, for example, attribute information may be grouped and the group may be associated with the attribute arrangement plane.

A description will be given based on the flowcharts shown in FIGS.

The same results and effects as described above can be obtained by selectively grouping attribute information input in advance or based on a search result and associating the group with an arbitrary attribute arrangement plane. Further, by making a correction such as addition or deletion of the attribute information to the group, the attribute information associated with the attribute arrangement plane can be operated.

That is, a 3D model is generated (step S1).
51) Input attribute information (step S152), 3D
The viewpoint position, line-of-sight direction, and magnification of the attribute arrangement plane are set for the 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).

When displaying, 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 displayed at the viewpoint position of the attribute placement plane. The information is displayed on the display device 204 according to the information on the line-of-sight direction and the magnification (step S16).
2) It is.

(Setting of a Plurality of Attribute Placement Planes) Next, a case of setting a plurality of attribute placement planes for the same line of sight will be described. (A plurality of attribute placement planes are parallel to each other.) FIG. 17 is a flowchart showing a processing operation when setting a plurality of attribute placement planes for the same line-of-sight direction. FIG. 9 is a diagram showing a 3D model when a plurality of attribute arrangement planes are set for the same line of sight direction.

A case in which a plurality of attribute arrangement planes are set in the 3D model 1 shown in FIG. 7 so that the projection direction of the front view and the line of sight coincide with each other will be described.

As described above, the 3D model 1 is created (step S171), and in step S172, the attribute placement plane 212 (viewpoint position, line-of-sight direction, magnification), which is the first attribute placement 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 and 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.

Then, in step S173, attribute information as shown in FIG. 10A is input in association with the attribute arrangement plane 212, and when viewed from the line of sight of the attribute arrangement plane 212, FIG. ), It can be seen very easily and easily in two dimensions.

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 line of sight of the attribute arrangement plane 214 is parallel to the plane 201b of the front view, and the magnification is, for example, 1
The viewpoint position is set so as to include the center axis of the hole of the attribute arrangement plane 3D model. Note that the attribute arrangement plane 214 is represented by a square painted shape.

At this time, 3 viewed from the attribute arrangement plane 214
The D model 1 has a virtual plane 21 as shown in FIG.
4 is the cross-sectional shape of the 3D model 1 cut.

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 section shape of the 3D model 1 and the attribute information associated with the attribute placement plane are displayed.

Further, if the 3D model 1 is moved, rotated, or the like, a three-dimensional display can be performed as shown in FIG.

That is, when the attribute placement plane 214 is selected, the 3D model present 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. ((B) of FIG. 18)
3) The 3D model shape and attribute information of the area are not displayed.

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 viewing 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.

Further, a configuration may be employed in which a plurality of attribute arrangement planes in which the shape of the 3D model 1 looks the same are provided. 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. By associating the attribute information with each attribute arrangement plane, for example, by grouping and associating them, more easily viewable attribute information can be realized. For example, FIG. 21 is a plan view of the 3D model 1, in which attribute information relating to external dimensions is grouped. FIG.
Is a grouping of the attribute information related to the hole position and the hole shape in the above. The grouped attribute information is stored in the attribute placement plane 215 and the attribute placement plane 21 respectively.
6. 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.

(Grouping of Attribute Arrangement Planes) As many pieces of attribute information necessary for a drawing are placed, the number of attribute arrangement planes increases accordingly. When many attribute arrangement planes overlap, it becomes difficult for an operator who creates a model to continue working.

The next process operator (process designer,
It is difficult for a mold design / manufacturer, a measurer, etc.) to read the required dimensions, which takes time.

Therefore, by displaying only a plurality of necessary attribute arrangement planes in a group, the operator can perform the work efficiently.

Next, the grouping of attribute placement planes will be described with reference to the drawings.

FIG. 33 is a flowchart showing this series of processing operations.

The 3D model 1 shown in FIG. 7 is created, and a plurality of
One is created (step S401).

Next, an arbitrary attribute placement plane is selected from a plurality of attribute placement planes (step S402). One attribute arrangement plane may be one group.

The user checks whether the selected attribute placement plane is correct (step S403). If incorrect, the process returns to the selection of the attribute placement plane (step S402). If no mistake is found, proceed to the next step.

The selected plural or single attribute arrangement planes are grouped (step S404). The grouping means assigns a group identifier to each group, an attribute arrangement plane identifier to each attribute arrangement plane, and associates an attribute arrangement plane identifier of an attribute arrangement plane belonging to the group with the group identifier of the group. Realize. The group described later has a hierarchical structure (tree structure)
, It is possible that one group belongs to another group, and the group identifier is associated with another group identifier in the same column as the attribute arrangement plane identifier. The means for grouping is not limited to this. Hereinafter, the grouping process refers to making an attribute arrangement plane (or group) belong to an arbitrary group, and storing information on the dependency relationship in the internal storage device 201 or the external storage device 202.

The color of the frame of the attribute arrangement plane changes for each group (step S405). In the present embodiment, the group is identified by changing the color of the frame of the attribute arrangement plane for each group. However, other means, such as identification of the entire attribute arrangement plane or the difference by hatching of the frame, The identification may be performed by displaying the fact in the vicinity.

The attribute storage plane of the group is determined by the internal storage device 201 or the external storage device 2.
02 (grouping process) (Step S40)
6).

Then, display control of display / non-display of the grouped attribute arrangement planes is performed (step S40).
7). This display / non-display is performed collectively (simultaneously).

FIG. 34 shows a single attribute placement plane.
It is a flowchart which shows a series of processing operation | movement which belongs to the already created group.

First, an attribute arrangement plane to be added to a group is selected (step S441).

A group to which the selected attribute placement plane belongs is selected (step S442). Note that the selection of the attribute arrangement plane (step S441) and the selection of the group (step S442) may be performed in reverse order.

A grouping process is performed (step S44)
3).

The color of the frame of the attribute arrangement plane is changed to the color of the group (step S444).

After the above processing, the image is displayed on the screen (step S
445).

Next, FIG. 35 is a flowchart showing a series of processing operations for displaying a non-displayed group.

In the browser bar, the icon of the attribute arrangement plane or the icon of the group to be displayed is selected (step S431).

The browser bar is an area where information such as the relevance of the attribute arrangement plane displayed together with the display of the 3D model is displayed and operated.

It is confirmed whether the selected attribute arrangement plane or group is correct (step S432).

The display of the selected group or the attribute arrangement plane alone is selected (step S433).

The selection process (step S433) is realized by selecting a “display” / “non-display” switch button and selecting it.

If a group is selected, an attribute placement plane belonging to the selected group is displayed. If an attribute placement plane is selected, the selected attribute placement plane is displayed (step S434).

Here, the attribute arrangement plane can be assigned (grouped) to a plurality of arbitrary groups. By making one attribute placement plane belong to a plurality of different groups, the required attribute placement plane can be viewed regardless of which group is displayed.

For example, assuming that the front view and the plan view are one group, and then the front view and the side view are one group,
When viewing either the plan view or the side view, the attribute information attached to the attribute placement plane in the front view can be seen, so that the work is easy to perform.

The above is also effective when grouping attribute placement planes based on attribute information. Various types of attribute information are associated with one attribute placement plane. When grouping attribute placement planes based on attribute information,
The attribute placement plane will belong to multiple groups.

For example, when there is a group of a plurality of attribute placement planes, no matter which group is displayed, if there is an attribute placement plane which is associated with attribute information which is not required to come out, If there is no function that can be grouped into a plurality of arbitrary groups, it takes time to display the attribute arrangement plane in each work, which hinders the work.

FIG. 36 is a flowchart showing a series of processing operations when hiding the attribute arrangement plane.

An attribute placement plane icon or group icon in the browser bar or an attribute placement plane belonging to the group on the screen is selected (step S421).

It is confirmed whether the selected one is correct (step S422).

The user selects to hide the selected group or attribute placement plane (step S423).

The attribute placement plane belonging to the selected group is no longer displayed on the screen (step S424).

Next, FIG. 37 is a flowchart of a series of processing operations when an attribute placement plane is created, and at the same time an attribute placement plane is created in a mode in which the attribute placement plane is automatically grouped.

First, at the same time as creating the attribute placement plane,
A mode in which the attribute placement planes alone constitute one group is selected in advance before creating the attribute placement planes (step S451).

In the process of selecting this mode, for example, a switching button (radio button) is provided on the screen, and the mode is selected by operating the button.

Create an attribute placement plane (step S45)

At the same time that the attribute placement plane is created, the attribute placement plane is grouped as a group having one attribute placement plane (S453).

Finally, display processing is performed (step S45).

(Position of Attribute Information) 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 has to enter a plurality of pieces of attribute information of the part of the 3D model to be expressed Are appropriately selected or grouped and associated with the attribute arrangement plane. 2
In the case of a three-dimensional drawing expression method, the position of the attribute information may be arranged in the area in the line of sight of the related attribute arrangement plane. In order to make full use of the merits of the 3D model, a device needs to be devised.

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, an operator who creates the model or an operator of the next process using the model (process designer, die design) The point is that for a creator, a measurer, etc.), the conversion work from 2D to 3D (which was mainly performed in the mind of the operator), which is necessary when handling a 2D diagram, can be omitted. . This conversion operation largely depends on the ability of the operator, and in this conversion operation, erroneous conversion due to erroneous conversion and loss of conversion time may occur.

In the 3D drawing, it is necessary to devise the display of the attribute information (position of the attribute information) at the time of stereoscopic display so as not to impair the merit of the 3D model in that it can be expressed in three dimensions.

The devised point will be described with reference to FIG.

FIG. 28 (a) is a perspective view of the 3D model 2 used for description, FIG. 28 (b) is a plan view of the 3D model 2, and FIG. 28 (c) is an attribute without devising the 3D model 2. FIG. 28D is a perspective view illustrating a state where information is added.
FIG. 5 is a perspective view obtained by devising the arrangement of attribute information.

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 displayed from the viewpoint of the attribute arrangement plane 218.

As for the input of the attribute information, if the arrangement planes 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. 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 expression (FIG. 28B). Information can be easily determined.

Thus, in the drawing form (three-dimensional drawing) in which the attribute information is added to the 3D model, not only the expression of the two-dimensional drawing but also the three-dimensional model, which is an advantage of the 3D model, while expressing the three-dimensional model. Since the attribute information can be easily determined, it can be used as a three-dimensional drawing (3D drawing).

It is desirable that the arrangement surface of the attribute information be the same as the attribute arrangement plane. In this example, a 3D model having a simple shape is used, but a 3D model having an actual more complicated shape is used.
When handling a D model, it is necessary to set a plurality of attribute arrangement planes in the same line-of-sight direction.

It is conceivable that a plurality of attribute arrangement planes and attribute information associated therewith are displayed at the same time, and then a desired attribute arrangement plane is selected or attribute information is selected.

At this time, if the position of the attribute information arrangement plane and the attribute arrangement plane is far apart, it becomes difficult to understand the relation 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.

Further, 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 simultaneously displaying the plurality of attribute placement planes and the attribute information associated therewith, if the attribute placement plane is created on the same plane, the placement plane of the attribute information is also on the same plane.
Even if the line of sight is shifted from the line of sight and viewed obliquely, the pieces of attribute information overlap, making it difficult to see. In the first place, since there is a large amount of attribute information when viewed from the same direction, it is divided into a plurality of attribute arrangement planes, and it is inevitable that attribute information overlaps when displaying attribute information at the same time.

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 easy to distinguish the attribute information in a perspective state.

(Magnification) 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.

FIG. 23 is a diagram showing a state in which a part of the 3D model 1 is enlarged and displayed. For example, as shown in FIG. 23A, by setting an 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.
FIG. 23B is a diagram showing a state where FIG. 23A is enlarged and displayed.

In the present embodiment, 3D-CAD in general, and 2D-CA in general, irrespective of the hardware constituting the 3D-CAD device or the method of constructing the 3D shape model.
Effective for D.

(Magnification and Size of Attribute Information) The size (height of characters and symbols) of the attribute information associated with the attribute arrangement plane is changed according to the magnification of the attribute arrangement plane.

The size (mm) of the attribute information is defined as the size in the virtual three-dimensional space where the 3D model exists. (It is not the size when displayed on the display device 204.) For example, the size of the attribute information is 3 mm on the attribute arrangement plane 211 (magnification 1). Attribute placement plane 2
FIG. 23C shows an example in which the character height is similarly set to 3 mm at 17 (magnification 5).

Since the attribute information associated with the attribute arrangement plane 217 is displayed at a display magnification of 5 times, its size is 1
5 mm.

[0200] In FIGS. 23B and 23C, a square line indicates a displayable range on the display device 204.

When the attribute information is arranged so as not to overlap,
Since the position of the attribute information is separated from the 3D model, it is difficult to understand the relationship between the shape and the attribute information related to the shape, 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 it is troublesome to change the display range in order to see the attribute information outside the displayable range.

If the user wants to display the image in a reduced size (the magnification is 1
If the character size is not changed to (less than), 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 cannot be determined.

Therefore, in consideration of the time when the attribute information is displayed, it is desirable to change the size of the information of the attribute information according to the magnification.

For this reason, it is preferable that the magnification and the size of the attribute information be approximately in inverse proportion. 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.

(Plural Selection of Attribute Placement Planes) In the above embodiment, when displaying attribute information associated with attribute placement planes, the number of attribute placement planes to be selected is limited to one. In view of the purpose, there is no problem even if a plurality of attribute arrangement planes are selected.

However, when a single attribute placement plane is selected, only one viewpoint position and one line-of-sight direction are provided, so that there is only one display method on the display device. You have to devise it because it becomes more than one. 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.

The display of the attribute information is modified so that the group can be easily identified by changing the color for each related attribute arrangement plane.

(Setting of Horizontal or Vertical Direction of Attribute Arrangement Plane) In the present invention, only the viewpoint position, line-of-sight direction and magnification are set on the attribute arrangement plane, and the horizontal or vertical direction of the attribute arrangement plane is set. Did not mention.

In the two-dimensional drawing, as shown in FIG. 25, rules are provided for the layout of the views (plan view, front view, 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.

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 expression viewed from a direction orthogonal to the outer surface of the 3D model (FIGS. 9 and 10)
(B) and (b) of FIG. 11 as well as the 3D model rotated from this state, and a three-dimensional representation viewed from an oblique direction ((a) of FIG. 10 and (a) of FIG. 11) is also possible. Becomes

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 corresponds to each direction of the display screen) Does not need to be specified otherwise. 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 represented, and the location of the part you have just viewed corresponds to the entire 3D model, and the location of the plan view and side view viewed from other viewing directions is easy. This is because there is no particular problem even if the display is performed without concern for the positional relationship between each line of sight in the horizontal direction or the vertical direction of the attribute arrangement plane.

However, in the 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. Without modifying the 3D drawing,
This is because there is a workplace or the like where it is sufficient to store and view in a two-dimensional image information electronic data format displayed by each attribute arrangement plane, and there are also workplaces that cannot be dealt with unless they are traditional paper drawings.

Assuming such a situation, the display as viewed from each line of sight must apply a rule such as a two-dimensional drawing.

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.

FIG. 30 shows a flowchart of the processing.

First, a 3D model is created (step S
301) Next, the viewpoint position, line-of-sight direction, and magnification are set for the 3D model, an attribute arrangement plane is created (step S302), and the horizontal direction (or vertical direction) of the attribute arrangement plane is specified. (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.

By specifying the horizontal direction (or the vertical direction) of the attribute placement plane, the 3D model displayed by selecting the attribute placement plane and the display position of the attribute information are uniquely determined.

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 of the already created attribute placement plane.

(Display Method of Attribute Information) In the above conventional example,
As an order for selectively displaying the attribute information input for the 3D model, first, an attribute placement plane is selected,
Next, the attribute information associated with the attribute arrangement plane is appropriately displayed. The description has been given in this order. However, the present invention is not limited to this method. The attribute information is selected, and then the attribute information is displayed. It is also effective to display the 3D model and the attribute information based on the position of the viewpoint, the line of sight direction, and the magnification of the associated attribute arrangement plane.

FIG. 31 (displayed from selection of attribute information) is a flowchart showing a series of processing operations.

In the state where 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 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 31
2. In this case, a front view is displayed as shown in FIG.

As a result, the selected attribute information and 3D
Since the relationship with the model is displayed two-dimensionally, it becomes easier to recognize.

In the above-mentioned conventional example, as the order of selectively displaying the attribute information input to the 3D model, first, an attribute placement plane or attribute information is selected, and then the attribute information is selected. The method of appropriately displaying the attribute information associated with these attribute placement planes based on the setting of the attribute placement plane associated with the placement plane and the attribute information has been described, but is not limited to this method. Geometric information of the 3D model (Ge
3) the attribute information associated with the geometric information, and further, the 3D model and the attribute information are displayed by the viewpoint position, line-of-sight direction, and magnification of the attribute arrangement plane associated with the attribute information. The display method is also effective.

FIG. 32 (displayed from selection of attribute information) is a flowchart showing a series of processing operations.

Geometric information of 3D model (edges, faces, vertices)
Select (Step 321) Display attribute information associated with the selected geometric information (Step 322)
If there is more than one associated attribute information,
You may display them all. Further, all the attribute information belonging to the attribute arrangement plane with which the attribute information is associated may be displayed.

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.

As described above, the 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.

Geometry information selection → related attribute information display (single) → displayed at display position of related attribute arrangement plane Geometric information selection → related attribute information display (single) → display position of related attribute arrangement plane display. Display all attribute information related to attribute placement plane Select geometric information → display related attribute information (multiple) → display at display position of related attribute placement plane (single attribute placement plane) Select geometric information → related Attribute information display (plural) → Display at the display position of the related attribute placement plane (single attribute placement plane). Display all attribute information related to attribute placement plane Select geometric information → display related attribute information (multiple) → display at display position of related attribute placement plane (multiple attribute placement plane) Select geometric information → related attribute Information display (plural) → Display at the display position of the related attribute arrangement plane (multiple attribute arrangement plane). Displays all attribute information associated with the attribute placement plane

[0229]

As described above, according to the present invention, when there is an attribute placement plane on which a large number of attribute information are placed, an attribute necessary for an operator to create and read a part of an object is provided. If only the arrangement planes are grouped, they can be displayed collectively, so that visibility is improved, work efficiency is improved, and attribute information of the portion can be quickly grasped.
