Description

The present invention relates to an information information device, an information information system, a control method and a program thereof.

It is common practice to insert dimensions into a drawing. The user specifies a desired element and inputs the dimensions.

For example, Patent Document 1 describes a technique for calculating a progressive dimension from a reference point to each element by selecting a plurality of target elements in a two-dimensional drawing. Further, Patent Document 2 describes a technique for inserting a progressive dimension while reducing the trouble of specifying an element.

Japanese Unexamined Patent Publication No. 5-165902 JP-A-2019-12435

However, in the techniques of Patent Document 1 and Patent Document 2, although progressive dimensions can be inserted all at once, dimensions between adjacent elements cannot be inserted all at once. To insert the dimensions between the elements, the user must manually specify the target elements one by one. The more elements there are, the more work is required to specify the elements, which is troublesome.

An object of the present invention is to provide a mechanism by which an object indicating a distance between adjacent elements can be easily inserted.

The present invention is a program that can be executed by an information processing apparatus that stores a plurality of elements.

A CAD (Computer-Aided Design) application is installed on the PC100. In addition, a dimension insertion program for calculating and inserting dimensions between adjacent elements in a CAD file is stored.

In the present embodiment, the dimension insertion program is stored and operates as an add-on program of the CAD application.

The CAD file is stored in the server 200. The CAD file stores the three-dimensional shape, size, and position / orientation of the parts constituting the design object in the three-dimensional space. In addition, the coordinates of the edges and end points of each component are stored.

A design that is represented by a three-dimensional shape is called a three-dimensional model. The CAD application has a function of creating a projection drawing (two-dimensional drawing) in which the three-dimensional model is projected from a predetermined direction and storing it as a CAD file in a drawing format. Information on which edge and which end point in the projection drawing is which edge and which end point of the 3D model on which the projection drawing is based is the ID of the edge stored in the memory of the device in which the CAD application is installed. It can be specified by the ID of the end point or the like. The above is the description of FIG.

Hereinafter, an example of the hardware configuration of the information processing apparatus according to the embodiment of the present invention will be described with reference to FIG.

In FIG. 2, 201 is a CPU that comprehensively controls each device and controller connected to the system bus 204. Further, the ROM 202 or the external memory 211 is necessary to realize a function executed by a BIOS (Basic Input / Output System) or an operating system program (hereinafter, OS) which is a control program of the CPU 201, and each server or each PC. Various programs described later are stored.

Reference numeral 203 denotes a RAM, which functions as a main memory, a work area, and the like of the CPU 201. The CPU 201 realizes various operations by loading a program or the like necessary for executing a process from the ROM 202 or the external memory 211 into the RAM 203 and executing the loaded program.

Further, 205 is an input controller, which controls input from an input device 209 (a pointing device such as a keyboard (KB) 209 or a mouse (not shown)). Reference numeral 206 denotes a video controller, which controls the display on a display such as a display 210 (for example, a CRT display). The display may be not only a CRT display but also another display such as a liquid crystal display. These are used by the user as needed.

Reference numeral 207 is a memory controller, which is connected to a hard disk (HD) for storing boot programs, various applications, font data, user files, edit files, various data, etc., a flexible disk (FD), or a PCMCIA card slot via an adapter.

The CPU 201 can display the outline font on the display 210 by executing the outline font expansion (rasterization) process on the display information area in the RAM 203, for example. Further, the CPU 201 enables a user instruction with a mouse cursor or the like (not shown) on the display 210.

Various programs described later for realizing the present invention are recorded in the external memory 211, and are executed by the CPU 201 by being loaded into the RAM 203 as needed. Further, a definition file and various information tables used when executing the above program are also stored in the external memory 211, and detailed description of these will be described later. The above is the description of FIG.

Next, an example of the functional configuration diagram in the embodiment of the present invention will be described with reference to FIG. The CPU of each device can execute each process by using the function of each function unit shown in FIG.

The CAD file storage unit 311 is a functional unit that holds and stores a CAD file acquired from the CAD file storage unit 321 of the server 200.

The display control unit 312 is a functional unit that controls the application so as to insert and display the dimensions calculated by the dimension calculation unit 315.

The dimension reference line selection unit 313 is a functional unit that selects the dimension reference line. For example, the clicked straight line element is selected as the dimension reference line.

The dimension reference line is a line used to specify an element to be referred to when calculating a dimension. In the present invention, for example, a straight line element orthogonal to the dimension reference line is specified as a target element for dimension calculation.

The element specifying unit 314 is a functional unit that specifies the target element for the dimension calculation. For example, the end point of the line segment intersecting the dimension reference line is specified as the target element.

The dimension calculation unit 315 is a functional unit that calculates the dimensions between the target elements. The above is the description of FIG.

Next, the flow of processing in the embodiment of the present invention will be described with reference to FIG. The process of FIG. 4 is executed by the CPU 201 of the PC 100 by using the functions of the CAD application and the dimension insertion program.

At the start of step S401, the CAD application assumes that the CAD drawing file is open. As shown in the drawing information 500 of FIG. 5, a plurality of views (view ID 502) are stored in association with each other in the drawing, and the coordinates 503 of the views are stored. Note that 501 is the name of the drawing.

The view is information that defines the projection direction and the three-dimensional model to be projected when displaying the projection drawing. Views are created for each specified projection direction based on user interaction with the CAD application. An example of the view is shown in 700 of FIG. In 700 of FIG. 7, four views (View001 to 004) are displayed on the two-dimensional drawing.

Further, an example of the information held by the view is shown in the view information 510 of FIG. Each view holds a view ID 511 that can identify the view, a CAD file name 512 indicating a three-dimensional model projected on the view, and a projection direction 513.

It is also possible to create a line segment sketch such as a line segment for each view. As shown in the line segment information 600 (FIG. 6), the line segment sketch information on the drawing holds the line segment sketch ID (sketch ID 602), its end point coordinates 603, and the view ID 601 of the view to which the sketch belongs. There is.

In step S401 of FIG. 4, the dimension insertion program accepts the selection of the dimension reference line. Specifically, in response to the reception of the line segment selection operation, the ID of the line segment is specified from the line segment information 600, and the dimension reference line information 610 on the RAM 203 (specifically, sketch ID 611 / FIG. 6). ), The selected line segment is specified as a dimension reference line and stored.

A display example of the selected dimension reference line is shown in FIG. 710. 710 shows a state in which View001 is enlarged and displayed.

Further, since the sketch ID 611 and the end point coordinates 612 in the dimension reference line information 610 are the same as those of 602 and 603 of FIG. 6, the description thereof will be omitted.

In step S402, the dimension insertion program refers to the view ID 601 of the line segment information 600 and identifies the view ID to which the dimension reference line belongs.

The specific processing in step S402 will be described. The dimension insertion program targets the currently active sheet (drawing) on the drawing being developed by the CAD application, and identifies the ID of the line segment sketch existing on all the views on the sheet. Then, the ID of the acquired line segment is compared with the ID of the dimension reference line information 610 specified in step S401, and the view indicated by the view ID 601 to which the matching line segment belongs is designated as the view to which the dimension reference line belongs.

In step S403, the dimension insertion program acquires the edge from the view to which the dimension reference line belongs, which is identified in step S402.

For example, the ID of the edge of the three-dimensional model corresponding to the target view and the three-dimensional coordinates are requested from the CAD application and acquired (522, 523 of the edge information 520 in FIG. 5). Then, the dimension insertion program calculates the two-dimensional coordinates on the projection surface when the three-dimensional coordinates are projected from the projection direction (524 in FIG. 5).

The edge information 520 is an example of the coordinates of the edge. In the CAD file shown in the CAD file name 521, the coordinates 523 of both ends in the three-dimensional space of each edge 522 are held. The edge information is stored in the external memory 211 of the server 200 and the PC 100 for each CAD file.

In the present embodiment, in step S402, the dimension insertion program requests and acquires the ID and the three-dimensional coordinates of the edge projected in the view (projection drawing) to which the dimension reference line belongs from the CAD application. To do. It is assumed that the CAD application that has received the request executes the determination of which edge is projected / not projected (the process of identifying the projected edge). The CAD application determines, for example, an edge represented by a hidden line or the like, which is hidden by another part or surface in the projection direction, is not subject to coordinate acquisition.

In step S404, the dimension insertion program refers to the edge information 520 and identifies an edge orthogonal to the dimension reference line belonging to the view in the view to which the edge belongs among all the edges in the view to which the dimension reference line belongs. To do. That is, on the projection plane of each projection drawing, the projection line of the edge orthogonal to the dimension reference line is specified.

In step S405, the dimension insertion program stores the coordinates of the intersection of the edge, the dimension reference line, and the edge identified in step S404. The intersection coordinates stored here are two-dimensional coordinates on the drawing when the lower left end point coordinates of the sheet (drawing) are set to X, Y = 0,0. Examples of coordinates are shown in 620 of FIG. 6 and 710 of FIG.

In step S406, the dimension insertion program calculates the distance between the intersections identified in step S405 and sorts them in ascending order of distance.

In step S407, the dimension insertion program specifies the intersections whose order after sorting is immediately before and immediately after as adjacent intersections. In addition, each edge that intersects the dimension reference line that forms the adjacent intersection is specified as an adjacent edge.

In step S408, the dimension insertion program identifies endpoints located closer to the insertion position of the dimension than the dimension reference line for all the edges identified in step S407. With the dimension reference line as the boundary, which side is the insertion position of the dimension is determined by the user operation.

Specifically, the dimension insertion program waits in step S408 until it accepts a mouse click operation on the drawing. When the mouse click operation is accepted, the two-dimensional coordinates (position of 721 shown in 720 of FIG. 7) on the drawing on which the click operation is performed are specified. That is, it is a designated reception process that accepts the designation of the position where the dimension is inserted.

Then, among the end points of the edges specified in step S407, the end points on the two-dimensional coordinate side where the mouse click is performed are specified with the dimension reference line as a boundary.

For example, the vertical distance from the dimension reference line to the coordinates of the mouse click is specified, and the direction from the dimension reference line to the coordinates of the mouse click is specified.

The dimension insertion program specifies the direction perpendicular to each end point from the dimension reference line among the end points of each edge specified in step S407. Then, among the end points, the end points in a direction similar to the direction from the dimension reference line toward the coordinates clicked by the mouse are determined as the end points used as the dimension calculation reference. That is, it is determined as the drawing position of the extension line.

The direction perpendicular to each end point from the dimension reference line is shown in 722 of FIG.

An example of the identified endpoints and their coordinates is shown in FIG. 720. Here, it is assumed that the dimension insertion program specifies four end points of X, Y = 10,45, X, Y = 30,45, Y = 50,38, and Y = 60,38.

Further, the dimension insertion program determines the insertion position of the dimension value and stores it in the dimension value display coordinate 633.

An example will be described for determining the insertion position of the dimension value. First, the dimension insertion program specifies the coordinates of the intermediate position on the dimension reference line for each of the coordinates of two adjacent intersections stored in step S620 and sorted in the order of closeness.

Then, the vertical distance between the coordinates for which the mouse click is received and the normal reference line in step S408 is acquired from the memory, and the positions separated from the dimension reference line in the vertical direction by the distance from each intermediate position as a starting point. Is determined as the insertion position of the dimension value. The determined value is stored in association with each pair of end points (dimension value display coordinate 633) specified based on the pair of each intersection. An example is shown in the dimension value display coordinates 633 of FIG.

The dimension insertion program stores the specified adjacent end points as elements to be inserted into the dimensions in the external memory 211.

For example, as shown in the dimension insertion target 630 of FIG. 6, the XY coordinates of the two adjacent end points to be calculated and inserted are stored in the dimension auxiliary line coordinate 632. Further, the dimensional auxiliary line coordinates 632 are stored in association with the ID 631. ID631 is information for uniquely identifying the extension line coordinates 632.

In step S409, the dimension insertion program inserts into the drawing a dimension object (eg, extension line, dimension line, dimension text) indicating the dimensions between the endpoints of adjacent edges identified in step S408. Request from the CAD app.

Specifically, the dimension insertion program calculates the dimension in the direction of the dimension reference line between each dimension auxiliary line coordinate 632, and inserts the text indicating each calculated dimension value at the position of the dimension value display coordinate 633. Instruct the CAD app to do so.

The CAD application that receives the instruction calculates the dimension between each end point in the direction of the dimension reference line, and inserts the dimension value, the dimension line, and the dimension auxiliary line.

An example of dimension lines and dimensional information is shown in FIG. 630. Further, an example of the display with the dimensions inserted is shown in 720 of FIG.

The dimension insertion program refers to a setting value (not shown) stored in the external memory, and if the setting value is set to "delete the dimension reference line after inserting the dimension", select in step S401. Instruct the CAD app to remove the accepted dimension reference line from the drawing. The CAD application that receives the instruction deletes the dimension reference line from the drawing. When the set value is set to "do not delete the dimension reference line after inserting the dimension", the instruction to delete the dimension reference line is not given. The above is the description of the first embodiment.

As described above, according to the present invention, it is possible to provide a mechanism capable of easily inserting an object indicating a distance between adjacent elements.

Next, a second embodiment of the present invention will be described with reference to FIG. The description of the process that overlaps with the description of the above-described embodiment will be omitted.

In the second embodiment, when the element for which the dimension is calculated cannot be specified, the user is notified of the fact that the element could not be specified and the reason thereof.

Specific processing will be described. The dimension insertion program determines whether the line segment selected in step S401 is a straight line. If it is a straight line, the process proceeds to step S402. If it is not a straight line, it is noted that the dimension reference line could not be specified because the selected element was not a straight line element, as shown in 800 in FIG. That is, the notification screen is displayed to select the straight line element as the dimension reference line.

Further, the dimension insertion program determines in step S408 whether or not there is an edge orthogonal to the dimension reference line, and if there is no orthogonal edge, as shown in 810 of FIG. 8, it is determined that there is no orthogonal edge. Notice. That is, it notifies that the calculation target of the dimension cannot be specified because there are no orthogonal edges.

Further, the dimension insertion program determines in step S408 whether or not there are two or more edges intersecting the dimension reference line. When there are no two or more intersecting edges, it is notified that there are no two or more intersecting edges, as shown in 820 of FIG. That is, it notifies that the calculation target of the dimension cannot be specified because there are no two or more intersecting edges. The above is the description of the second embodiment.

As described above, according to the second embodiment, when the element for which the dimension is calculated cannot be specified, the fact that the element could not be specified and the reason thereof can be easily confirmed.

Next, a third embodiment of the present invention will be described with reference to FIG. The description of the process that overlaps with the description of the above-described embodiment will be omitted.

In the third embodiment, the user can be made to confirm the element for which the dimension is calculated in advance.

Specific processing will be described. In step S404, the dimension insertion program instructs the CAD application to identify and display the edge that intersects the dimension reference line specified in the step. The CAD application that receives the instruction specifies the coordinates of both ends of the edge, connects those coordinates, generates a sketch of the same length and shape as the edge, and at the same position as the edge on the drawing, the said Display so that it overlaps the edge. The CAD application changes the color of the sketch to a predetermined color (eg, red) so that the sketch can be distinguished from the projection line. An example is shown by a broken line in 900 of FIG.

That is, the user is notified that the edge serves as a dimensional calculation standard.

After step S408, the dimension insertion program identifies and displays the end points identified in step S408 so that they can be recognized as the dimensional calculation reference.

Specifically, the dimension insertion program instructs the CAD application to place an object having a predetermined shape (in the present embodiment, the shape of "x") at each coordinate of the extension line coordinate 632. The CAD application that receives the instruction generates an object having the predetermined shape, and arranges and inserts it at each coordinate on the drawing. An example is shown in 910 of FIG.

After step S408, the dimension insertion program displays a confirmation dialog as shown in 920 of FIG. The confirmation dialog is a screen for asking the user to confirm whether the dimensions may be calculated / inserted based on the elements and coordinates specified by the processes of steps S401 to S408.

When the pressing of the "Yes" button is accepted, the process proceeds to step S409, and after the process of S409 is executed, each object shown in 900 and 910 of FIG. 9 (indicated by the broken line, the element to be dimensioned is identified. Instruct the CAD app to delete the sketch to be displayed and the "x" object that indicates the end point). According to the instruction, the CAD application deletes the target object.

When the pressing of the "No" button is accepted, the process is returned to the previous step S401 without executing the process of step S409, and the selection of the dimension reference line is deselected. Further, each object shown in 900 and 910 of FIG. 9 (a sketch for identifying and displaying an element to be dimensionally calculated and an object of "x" indicating an end point shown by a broken line) is deleted. According to the instruction, the CAD application deletes the target object.

As described above, according to the third embodiment, the user can be made to confirm the element for which the dimension is calculated in advance.

Next, a fourth embodiment of the present invention will be described with reference to FIGS. 10 and 11. The description of the process that overlaps with the description of the above-described embodiment will be omitted.

In the fourth embodiment, the dimension is inserted into the three-dimensional space by using the solid displayed by the CAD application in three dimensions.

At the time of step S1001, the CAD application has already read the CAD file, expanded it on the memory, and as shown in 1100 of FIG. 11, has a three-dimensional shape in a three-dimensional space (a space composed of three axes of XYZ). It is assumed that the CAD file (a three-dimensional model in which the position / orientation and the shape are stored by the CAD file) is displayed.

In step S1001, the dimension insertion program selects the edges of the part in the 3D model being displayed. That is, the selection of the element (three-dimensional element) of the file stored as a three-dimensional object is accepted.

Specifically, the ID of the component 1111 (see 1110 in FIG. 10) selected in the CAD application is acquired from the CAD application, and the edge of the component selected in the CAD application (edge 1121 in 1120 in FIG. 11). ID and coordinates (for example, three-dimensional coordinates of both ends of the edge) are acquired from the CAD application and stored in the memory. The edge selected here is the dimension reference line in the fifth embodiment.

In step S1002, the dimension insertion program identifies the faces of the parts that intersect the edges. Here, a component other than the component that holds the edge selected in step S1001, and the ID of the surface intersecting the edge (example: ID of each surface 1141, 1142, 1143, 1144 in 1140 of FIG. 11) and shape. , Requests the vertex coordinates (three-dimensional coordinates) of the surface from the CAD application. The CAD application acquires the ID, shape, and vertex coordinates of the surface that have responded in response to the request and stores them in the memory.

In step S1003, the dimension insertion program requests the CAD app for the intersection coordinates of the edge selected in step S1001 and the surface that intersects the edge (eg, intersections 1131, 1132, 1133, 1134 in 1130 of FIG. 11). Get it and store it in memory.

In step S1004, the dimension insertion program identifies a newly selected surface (eg, surface 1155 in 1150 of FIG. 11) by user operation. Specifically, the ID of the surface selected by the CAD application by the user operation is acquired from the CAD application.

In step S1005, the dimension insertion program includes edges composed of the surfaces (1141-1144) identified in step S1002 and the surfaces 1155 identified in step S1004 (eg, edges 1151, 1152, 1153 in FIG. 11). The information of 1154) is inquired to the CAD application, acquired, and stored in the memory. The edge information acquired here is the ID and shape of the edge, and the coordinates (three-dimensional coordinates) of the end points.

In step S1006, the dimension insertion program acquires the end point coordinates of each edge acquired in step S1005 from the memory and stores them as a list.

In step S1007, the dimension insertion program accepts the designation of three-dimensional coordinates. Specifically, the three-dimensional coordinates for which the click operation is accepted in the CAD application are acquired. When the coordinates do not appear on the surface selected in step S1004, the coordinates are stored in the memory. Here, for example, it is assumed that the click operation is performed at the position of the mouse cursor at 1160 in FIG.

In step S1008, the dimension insertion program specifies the three-dimensional coordinates of the projected line when the edge 1121 selected in step S1001 is projected in a direction perpendicular to the surface 1155 selected in step S1004. Then, from the list of endpoints in step S1006, the endpoints on the coordinate side designated in step S1007 are specified with the projection line as a boundary.

Specifically, the CAD application is requested to generate a plane 1165 (FIG. 11) in which the edge 1121 is stretched in a direction perpendicular to the surface 1155, and the CAD application generates the plane 1165. Then, from the list of endpoints in step S1006, the endpoints on the coordinate side designated in step S1007 are specified with the surface as a boundary.

In step S1009, the dimension insertion program calculates the distance of the end points specified in step S1008 in the direction of the edge selected in step S1001, and sorts them in order of closeness. That is, adjacent end point elements (planes holding adjacent end points) are specified.

In step S1010, the dimension insertion program stores the sorted plurality of endpoints by two in ascending order of distance. Then, the CAD application is instructed to insert (arrange) an object indicating the dimension between the two endpoints in the three-dimensional space.

Specifically, the coordinates of the intersection of the plane 1165 and each edge of 1151 to 1154 are specified. Then, from the intersection coordinates, the direction V toward the end points 1161 to 1164 identified in step S1008 on the edge holding the intersection is specified. After that, the CAD application is instructed to create a line segment (dimension auxiliary line) extending in the direction V from each end point of 1161 to 1164, and the CAD application creates a line segment according to the instruction.

The length of the extension line extending from each end point of the end points 1161 to 1164 is the length from the end point 1161 which is the farthest from the plane 1165 to the coordinates separated by a predetermined distance in the direction V (for example, the coordinates separated by 10 cm). Instruct the CAD app to do so. The distance to the end point farthest from the plane 1165 and the length of the extension line are calculated by the dimension insertion program and transmitted to the CAD application.

In addition, the CAD application is instructed to calculate the dimension between the adjacent dimensional extension lines (the dimension in the direction orthogonal to the two adjacent dimensional auxiliary lines), and the CAD application follows the instruction between the dimensional auxiliary lines. Calculate the dimensions.

Further, the dimension insertion program instructs the CAD application to create a line segment (dimension line) perpendicular to both of the adjacent dimension auxiliary lines, and the CAD application creates each dimension line according to the instruction.

Further, the dimension insertion program instructs to superimpose the dimension value calculated by the CAD application on the midpoint of each dimension line. Specifically, a plane of a predetermined size parallel to the plane 1165 is created on each dimension line, and the CAD application is instructed to transfer the text indicating the dimension value to the plane, and the CAD application follows the instruction. Create planes and transfer text. The figure of the result of the dimension insertion is shown in 1170 of FIG.

After inserting the dimensions, the dimension insertion program refers to the setting information (not shown) stored in the memory of the PC 100. When the setting information is set to "delete unnecessary elements after inserting dimensions", for example, the CAD application is instructed to delete the component 1111 and the plane 1165 of FIG. The CAD application deletes the component 1111 and the plane 1165 according to the instruction. The above is the description of the fourth embodiment.

As described above, according to the fourth embodiment, it is possible to provide a mechanism capable of easily inserting an object indicating the distance between adjacent elements in the display area for displaying a solid. Become.

Next, a fifth embodiment will be described with reference to FIG. The description of the process that overlaps with the description of the above-described embodiment will be omitted.

In the fifth embodiment, a mechanism is provided in which an object indicating the distance between adjacent elements can be easily inserted by switching which element to calculate the dimension according to the mode.

Further, a mechanism for calculating and inserting dimensions is provided not only for edges orthogonal to the dimension reference line but also for all intersecting edges.

Immediately after step S406, the dimension insertion program refers to the mode information (not shown) stored in the external memory. The mode information holds a value indicating whether the mode is to insert the dimension between the intersections or the mode to insert the dimension between the edges.

When the mode information indicates the mode for inserting the dimension between the edges, the dimension insertion program shifts the process to step S406, and performs the dimension calculation and insertion process. The state of the insertion result is shown in 1210 of FIG.

On the other hand, when the mode information indicates a mode for inserting the dimension between the intersections, the CAD application is instructed to calculate the linear distance between the adjacent intersections and insert the value of the distance as the dimension between the intersections. .. For example, the dimensions between the intersections 1201, 1202, 1203, and 1204 shown in 1200 in FIG. The CAD application calculates and inserts the dimensions according to the instruction. The state of the insertion result is shown in 1200 of FIG. The above is the description of the fifth embodiment.

According to the fifth embodiment, it is possible to easily insert an object indicating the distance between adjacent elements by switching which element to calculate the dimension according to the mode.

Further, the dimensions can be calculated and inserted not only for the edges orthogonal to the dimension reference line but also for all the intersecting edges.

As described above, according to the present invention, it is possible to provide a mechanism capable of easily inserting an object indicating a distance between adjacent elements.
