Description

  The present invention relates to a drawing process for creating two-dimensional CAD data using three-dimensional CAD data, and in particular, an information processing apparatus that outputs a layer in units of construction and creates two-dimensional CAD data, a control method for the information processing apparatus, and a program About.

  Even now, with the spread of 3D CAD applications, the design by creating 3D shape data (shape data) has progressed, the position as the final product in the design is 2D CAD data (drawing data), that is, printed on paper as before. It is a drawn drawing (paper drawing). This is due to the fact that paper drawings are used not only in the culture and customs of domestic companies over many years, but also in exchanges with government agencies.

  Even if all design information is included in the shape data, drawing data must still be created based on the designed shape data, so the 3D CAD application generally has a function to create drawing data from shape data. Is provided. However, it cannot be said that the drawing creation function of the three-dimensional CAD application, for example, functions such as drawing notation (dimension expression and instruction symbol) sufficiently satisfy the functions of the two-dimensional CAD application.

  Therefore, many 3D CAD applications have the function of projecting and displaying the outline of the shape data onto the drawing data, thereby efficiently creating the drawing data with only the outline and importing it into the 2D CAD application. The procedure of finishing drawing data on the application is taken.

  When creating drawing data using a two-dimensional CAD application, a display layer generally called a layer (for example, an outline of component data or a drawing notation is drawn on a slide film and all slide films are displayed in an overlapping manner) is used. Work is done while assigning individual contour lines and drawing notation to individual layers.

  For example, in Patent Document 1 below, multiple layers are created in advance in the drawing data. When a new contour line is assigned to a layer in the course of the work, an unused layer is searched and the display setting of the layer is automatically set. The mechanism to change to is disclosed.

JP-A-8-185416

  However, in the standard function of the 3D CAD application, the outline of the entire shape data is assigned to one layer. Therefore, when working with the 2D CAD application, an arbitrary outline can be selected from the imported outline. There is a problem that the operation of manually selecting the component unit unit (for example, for each assembly data) and reassigning it to a plurality of layers occurs.

  As the component parts constituting the shape data, there are part data constituting the three-dimensional model and assembly data for managing the positional relationship of the component parts. The assembly data and the part data are constructed in a vertical relationship. For example, as shown in FIG. 21, one shape data is constructed from a plurality of assembly data and part data. In a two-dimensional CAD application, it is often desirable to perform processing in units of components, such as assembly data, rather than performing drawing notation on the entire shape data, so reassign them to multiple layers so that they are in units of components. Work has occurred.

  In the mechanism disclosed in Patent Document 1, it has been realized that a contour line or the like is efficiently allocated to drawing data for which a plurality of layers are prepared. There is no solution to selecting a line for any component part.

  A drawing is made up of a number of contour lines, and if it is possible to avoid the task of selecting a contour line from any of these components and assigning it to a layer, the drawing data from the 3D CAD application can be avoided. It is expected to shorten the drawing data creation time by the two-dimensional CAD application.

  The present invention has been made to solve the above-described problems. When outputting drawing data that can be captured by a two-dimensional CAD application from a three-dimensional CAD application, an arbitrary component unit can be used for the contour line of shape data. An object of the present invention is to provide a mechanism for improving the efficiency of drawing data creation work in a two-dimensional CAD application by assigning layers.

In order to achieve the above object, an information processing apparatus of the present invention stores part data for displaying three-dimensional shape data indicating a three-dimensional shape of a design and assembly data for managing the part data. comprising a storage unit for an information processing apparatus for managing the three-dimensional shape data for each stored component data in the SL憶unit, and the contour line extraction means for extracting a contour line of the component data, before for each stored assembly data to listen憶means, and layer forming means for forming a layer for constituting the two-dimensional drawing data showing a planar shape of the designed object, the contour extracted by the contour extracting means , and a layer assignment means for assigning relative layer created by the layer forming means, the layer assignment means, said assembly data pipe When assigning contour of the component data to the layer created by the layer forming means, with respect to the assembly data are created corresponding to the layer, and allocates the contour of the component data .

  According to the present invention, when shape data created by a 3D CAD application is output to drawing data that can be captured by the 2D CAD application, it can be assigned to a layer in units of components designated by the user. There is an effect that it is possible to avoid reassignment to individual layers on the CAD application.

Note that the module configurations of the various terminals or servers in FIG. 3 are merely examples, and it goes without saying that there are various configuration examples depending on applications and purposes.

  The information processing apparatus 101 includes a shape data storage module 301, a layer management module 302, a screen display module 303, and a table management module 304.

  The shape data storage module 301 is a module for storing shape data created by a three-dimensional CAD application (component storage means). The shape data stored by the shape data storage module 301 is stored in the external memory 211 or the like of the information processing apparatus 101, and is read by the shape data storage module 301 as necessary.

  The table management module 304 is a module for storing and updating various tables in FIG. Various tables are stored in the external memory 211 and read out to the RAM 203 as necessary.

  The server 102 includes a shape data storage module 306. The shape data storage module 306 is the same as the shape data storage module 301 of the information processing apparatus 101 described above. The shape data storage module 301 of the information processing apparatus 101 is used when the information processing apparatus 101 stores and manages the shape data, and the shape data storage module 306 of the server 102 is used when the shape data is stored and managed by the server 102. To do. In the present embodiment, description will be made assuming that the shape data storage module 301 of the information processing apparatus 101 is used.

  Next, a series of processing performed by the information processing apparatus 101 in the embodiment of the present invention will be described using the flowchart shown in FIG. Note that steps S401 to S412 are performed under the control of the CPU 201 in the information processing apparatus 101.

  Note that a program for causing the information processing apparatus 101 to execute this processing may be prepared as a part of a three-dimensional CAD application installed in the information processing apparatus 101 or as an add-on program, or a three-dimensional CAD application. Alternatively, it may be prepared as a program installed separately.

  When the processing shown in FIG. 4 is performed, the CPU 201 of the information processing apparatus 101 is in a state in which a three-dimensional CAD application can be operated. In the present invention, the contour lines of the parts displayed in the drawing data are assigned to arbitrary layers while referring to the vertical relationship of the parts.

  First, in step S401, the information processing apparatus 101 reads arbitrary shape data by a user's operation of the three-dimensional CAD application and displays it on the three-dimensional CAD application.

  In step S <b> 402, when the information processing apparatus 101 receives an instruction to start the layered output program from the user, the information processing apparatus 101 reads the layered output program from the external memory 211 and starts it. The layered output program may operate as one of the menus of the 3D CAD application, or may operate as a program different from the 3D CAD application.

  In step S403, the information processing apparatus 101 identifies each view (for example, a front view, a plan view, and a right side view in the case of being created by the third trigonometry) as a view, which is stored in the shape data read in step S401. ) Are acquired and stored in the view table 1000 (see FIG. 10). Specifically, an identification number is stored for each view identified as No 1001 in the view table 1000, and the identified view name is stored as a view name 1002. The storage result is as shown in FIG. “View-1” is a front view, “View-2” is a plan view, and “View-3” is a right side view. In this embodiment, the description is limited to “View-1”, but the operation is the same for other views.

  The view table 1000 (see FIG. 10) is composed of No 1001 indicating the record number of the view and a view name 1002 indicating the identification name of the view.

  In step S404, the information processing apparatus 101 acquires component parts such as assembly data and part data constituting the shape data read in step S401, and performs layer table processing for all the views stored in the view table 1000 in step S403. 1010 (see FIG. 10). Specifically, the record number is stored in the ID 1011 of the layer table 1010, and the view name 1002 stored in step S403 is stored in the view name 1012. Further, the record number is stored in the reference ID 1013, the component name corresponding to the hierarchical relationship path of the component is stored in the component name 1014, and the folder path of the component is stored in the file path 1015.

  The layer table 1010 (see FIG. 10) includes an ID 1011 indicating a record number, a view name 1012 indicating a view name to be processed, a reference ID 1013 indicating which component part is included in the layer, and a configuration position in the entire structure. The component name 1014 indicates the file path 1015 indicating the storage location of the component, and the layer name 1016 indicates the name of the layer when creating the layer.

  The component name 1014 corresponds to a configuration position for a specific component in the entire structure. For example, if the file name read in step S401 is “Structure” and the component name located below it is “Unit01”, the component name is expressed as “Structure / Unit01-1”. In this case, “−1” is an identification number for convenience when a plurality of “Unit01” is arranged. “/” Is a delimiter signifying a vertical relationship between files, but is not necessarily limited to this. In this case, “Structure” is higher than “Unit01-1”. In the present embodiment, “Structure” is omitted from the data stored in the component name 1014.

  In step S405, the information processing apparatus 101 creates a layer name by combining the value of the component name 1014 and the file name read in step S401 with respect to the layer table 1010 created in step S404, and stores the layer name in the layer name 1016. .

  The storage results in steps S404 and S405 based on the shape data composed of the component parts as shown in FIG. 21 are as shown in FIG. 12 with the delimiters replaced. Of the stored information, the reference ID 1013 and the layer name 1016 may be changed by a procedure described later.

  In step S406, the information processing apparatus 101 creates a check box table 1020 (see FIG. 10) based on the layer table 1010 created in step S405. Specifically, first, the document type of the component is acquired by the file path 1015 of the layer table 1010. When the extension of the document is “SLDASM”, it is identified as assembly data, and when the extension is “SLDPRT”, it is identified as component data. The ID 1011 being processed is stored in the ID 1021 of the check box table 1020, the upper part is identified based on the component name 1014 of the component being processed, and the ID 1011 of the record corresponding to the upper part is stored in the parent ID 1022. When the document type of the component being processed is assembly data, “1” is stored in the check 1023, and when the document type is component data, “0” is stored in the check 1023.

  For example, “1” in the ID 1011 of the layer table 1010 shown in FIG. 12 is the read file in step S401, so the value of its own ID 1011 is stored in the parent ID 1022 of the check box table 1020. On the other hand, among the components 1011 in the layer table 1010 shown in FIG. 12, the component parts “2” to “5” have the upper part “Unit01”, so “1” is stored in the parent ID 1022. Since the ID 1011 is “6” and the upper part is “Unit 02”, “5” is stored in the parent ID 1022. The storage result of step S406 is as shown in FIG.

  The check box table 1020 includes an ID 1021 indicating a record number, a parent ID 1022 indicating an ID 1011 of a higher-level component, and a check 1023 indicating whether or not there is a check box provided in a layer name designation dialog 1400 (FIG. 14) described later. The In the check 1023, “0” indicates that no check box is provided, “1” indicates that the check box is provided but the check is not performed, and “2” indicates that the check box is provided and the check is not performed. Indicates the status being made. These flags only need to be able to manage check boxes, and are not limited thereto.

  In step S407, the information processing apparatus 101 performs a process of accepting designation of a component to be output based on an operation from the user. Details of the layer name designating process are shown in FIG.

  In step S408, the information processing apparatus 101 creates a copy of the shape data as a temporary file in the current folder in order to edit the shape data read in step S401.

  In step S409, the information processing apparatus 101 performs a layer creation process based on the layer name 1016 of the layer table 1010 for the temporary file created in step S408. Details of the layer creation processing are shown in FIG.

  In step S410, the information processing apparatus 101 assigns drawing data to the layer created in step S409 in units of component names 1014 in the layer table 1010. Details of the layer assignment process are shown in FIG.

  In step S411, the information processing apparatus 101 stores the shape data, for which the layer assignment processing has been completed in step S410, in a file format that can be read by the two-dimensional CAD application, and stores it in the external memory 211. As the storage location, the location of the file path specified in step S510 described later is acquired from the RAM 203 and stored in the file path.

  In step S412, the information processing apparatus 101 deletes the temporary file created in step S408, ends the layered output program started in step S402, and ends this series of processing.

  Next, the layer name designation process will be described with reference to FIG. Note that steps S501 to S511 are performed under the control of the CPU 201 in the information processing apparatus 101.

  A program for causing the information processing apparatus 101 to execute this processing may be prepared as a part of a 3D CAD application installed in the information processing apparatus 101 or as an add-on program. What is a 3D CAD application? It may be prepared as a separately installed program.

  In step S501, the information processing apparatus 101 acquires the layer table 1010 created in step S405 and the check box table 1020 created in step S406.

  In step S502, the information processing apparatus 101 displays a user control layer name designation dialog 1400 (see FIG. 14) based on each table acquired in step S501. The configuration of the screen is not limited to this.

  When displaying the records in the layer table 1010 in ascending order, the layer name designation dialog 1400 displays a check box 1401 in a record in which “1” is stored in the check 1023 of the check box table 1020. The check box 1401 is displayed only in the assembly data record. When the check box 1401 is checked, the component managed by the assembly data is assigned to the same layer as the assembly data layer. By doing this, it is possible to divide layers not in parts data but in arbitrary components such as assembly data.

  The layer name designation dialog 1400 extracts only the document name from the file path 1015 of the layer table 1010 and displays it in the component name column 1402, and the layer name 1016 of the record of ID 1011 having the same value as the reference ID 1013 of the layer table 1010. Is displayed in the layer name column 1403.

  For example, based on the layer table 1010 of FIG. 12, when processing a record with ID 1011 “3”, the reference ID 1013 of the record with ID 1011 is “3”, so the layer name field for the record with ID 1011 “3” In 1403, a layer name 1016 stored in the record whose ID 1011 is “3” is displayed. If the reference ID 1013 of the record is “1”, the layer name 1016 stored in the record whose ID 1011 is “1” is displayed in the layer name column 1403. When the component name is displayed in the layer name designation dialog 1400, the paragraph is lowered and displayed every time it moves to a lower level in the vertical relation, and the background color is displayed for the line having the check box. A layer name designation dialog 1400 created based on the layer table 1010 of FIG. 12 is as shown in FIG.

  In step S503, the information processing apparatus 101 receives an on / off operation of a check box 1401 performed by the user with respect to the layer name designation dialog 1400 displayed in step S502. If it is determined that the check box 1401 is checked, the process proceeds to step S504, and if not, the process proceeds to step S506.

  In step S504, the information processing apparatus 101 performs update processing on the check 1023 of the check box table 1020 based on the on / off state of the check box 1401 received in step S503. For example, as shown in FIG. 15, among the components displayed in the layer name designation dialog 1400, when the check box 1401 of “Unit02.SLDASM” is changed from off to on, the check box table 1020 in FIG. As shown, the value of the check 1023 is updated to “2” for the record whose ID 1021 corresponding to “Unit02” is “5”. That is, the check box 1401 stores that the check has been made.

  In step S505, the information processing apparatus 101 updates the layer table 1010 when the check box table 1020 is updated in step S504. Details of the layer table update processing are shown in FIG.

  If the check box 1401 is not turned on / off in step S503, the process proceeds to step S506.

  In step S506, the information processing apparatus 101 determines whether the layer name column 1403 or the component name column 1402 portion of the displayed layer name designation dialog 1400 has been selected by the user. If it is determined that it has been selected, the process proceeds to step S507. If it cannot be determined that it has been selected, the process proceeds to step S508.

  In step S507, the information processing apparatus 101 selects the outline of the record in the layer name column 1403 or the component name column 1402 selected in step S506 on the drawing data of the three-dimensional CAD application. Perform the process. Details of the contour selection display process are shown in FIG.

  In step S508, the information processing apparatus 101 determines whether the pressing of the reference button 1404 is detected. If it is detected that the reference button 1404 has been pressed, the process proceeds to step S509. If not, the process returns to step S503.

  In step S509, when the information processing apparatus 101 accepts pressing of the reference button 1404 in step S508, the information processing apparatus 101 displays a file save dialog (not shown) for designating a save destination of drawing data that can be read by the two-dimensional CAD application. , Accept the designation of the folder to save from the user.

  In step S510, the information processing apparatus 101 performs reception processing of the file name to be saved in the file save dialog displayed in step S509, the folder to be saved and the file name to be saved are input, and a confirmation instruction is received from the user. In this case, a file path is created by combining the folder path and file name of the folder, and stored in the RAM 203. The file save dialog is closed.

  In step S511, the information processing apparatus 101 determines whether the execution button 1405 has been pressed. If it is detected that the execution button 1405 has been pressed, the layer name designation process is terminated and the process is returned to the caller. If not, the process waits until it is pressed.

  Next, the layer table update process will be described with reference to FIG. In addition, each step of S601 to S610 is performed under the control of the CPU 201 in the information processing apparatus 101.

  A program for causing the information processing apparatus 101 to execute this processing may be prepared as a part of a 3D CAD application installed in the information processing apparatus 101 or as an add-on program. What is a 3D CAD application? It may be prepared as a separately installed program.

  Here, as shown in the layer name designation dialog 1400 in FIG. 15, the case where the fifth record of the check box table 1020 in FIG. 15 is acquired with “Unit 02” checked is shown as an example. Steps S604 and S610 will be described.

  In step S601, the information processing apparatus 101 acquires records from the check box table 1020 in ascending order of ID1021.

  In step S602, the information processing apparatus 101 determines whether the value of the check 1023 of the record acquired in step S601 is “1” or “2”. That is, it is determined whether or not a check box exists in the acquired record. When it is determined that the value of the check 1023 is “1” or “2”, the process proceeds to step S603, and when it is determined that the value of the check 1023 is not “1” or “2”. Then, the process proceeds to step S605. If the above example is taken over, the value of the check 1023 of the record whose ID 1021 is “5” in the check box table 1020 is “2”. Therefore, since there is a check box, the process proceeds to step S603.

  In step S603, the information processing apparatus 101 determines whether the value of the record check 1023 acquired in step S601 is “2”. That is, it is determined whether or not the check box 1401 is checked. If it is determined that the value of the check 1023 is “2”, the process proceeds to step S604. If not, the process proceeds to step S605. Taking over the above example, the value of the check 1023 is “2”. Therefore, the process proceeds to step S604 to indicate that the check box 1401 is checked.

  In step S604, the information processing apparatus 101 performs update processing of the layer table 1010. Here, the record of ID 1011 of the layer table 1010 having the same value as the ID 1021 being processed for the check box table 1020 is specified, and the value of the reference ID 1013 is updated to the value of the ID 1011 of the record for the record. When the above example is taken over, the reference ID 1013 is updated to “5” in the record whose ID 1011 of the layer table 1010 is “5”. If the process is performed from the initial state, the reference ID 1013 does not change. The reference ID 1013 is for determining which record is assigned to the layer of the layer name 1016. Therefore, storing the ID 1011 of its own record in the reference ID 1013 indicates that it is assigned to the layer of its own layer name 1016.

  In step S610, the information processing apparatus 101 determines whether the record being processed in the check box table 1020 is the last record. That is, it is determined whether or not the processing of all the records in the check box table 1020 has been completed. If it is determined that the record being processed is the last record, the layer table update process is terminated and the process is returned to the caller. If not, the process returns to step S601. If the above example is taken over, since the ID 1021 being processed is “5”, the process returns to step S601.

  Next, as shown in FIG. 15, the case where the sixth record of the check box table 1020 in FIG. 15 is acquired with “Unit 02” checked as shown in FIG. 15 is taken as an example, step S605 to step S607. Will be explained. In step S601, a record whose ID 1021 in the check box table 1020 is “6” is acquired, and in step S602, the value of the check 1023 in the record whose ID 1021 in the check box table 1020 is “6” is confirmed. Since the value is “0”, which indicates that there is no check box, the process proceeds to step S605.

  In step S605, the information processing apparatus 101 determines whether the record being processed in the check box table 1020 is the component positioned at the top of the other component components. Specifically, the ID 1021 of the record being processed and the value of the parent ID 1022 of the record are compared to determine whether they are the same. It is understood that the same component is the highest-order component since there is no component corresponding to the top of the record. Therefore, the component positioned at the top does not belong to a layer other than its own layer name 1016, and the process proceeds to step S604. If the component is the highest position component, the process proceeds to step S604, and if not, the process proceeds to step S606. If the above example is taken over, since the parent ID 1022 of the record with ID 1021 of “6” is “5”, the process proceeds to step S606.

  In step S606, the information processing apparatus 101 acquires the on / off state of the check box 1401 for the check 1023 of the record with the parent ID 1022 of the record being processed, and determines whether the check box 1401 is on. That is, if the check box 1401 of the upper component is turned on, the record being processed needs to belong to the layer of the upper component, and thus the process proceeds to step S607. The on / off state of the check box 1401 is determined based on whether the check 1023 is “1” or “2”. “2” indicates ON. If the check box 1401 is on, the process proceeds to step S607, and if not, the process proceeds to step S608. The record set in the parent ID 1022 always has a check box 1401 because the document type is always assembly data. If the above example is taken over, the ID 1021 is “6” and the parent ID 1022 is “5”, so the record to be acquired is the value of the check 1023 of the record with the ID 1021 “5”, and here, “2” indicating check-on is acquired. Therefore, the process proceeds to step S607.

  In step S607, the information processing apparatus 101 acquires a record having the same ID 1011 as the ID 1021 being processed from the layer table 1010, and reflects the value of the parent ID 1022 of the record being processed in the reference ID 1013 of the acquired record. Taking over the above example, since the parent ID 1022 of the record whose ID 1021 is “6” in the check box table 1020 is “5”, “5” is stored in the reference ID 1013 of the record whose ID 1011 in the layer table 1010 is “6”. It will be. The stored result is as shown in a storage example 1501 in FIG. Further, for example, the processing is continued as it is, and the result of processing up to the seventh record is as shown in a storage example 1502 shown in FIG. In this way, when the “Unit 02” check box 1401 is checked, “Type 04” and “Type 05” positioned below “Unit 02” are assigned to the “Unit 02” layer.

  Next, as shown in the layer name designation dialog 1400 in FIG. 16, the case where the sixth record of the check box table 1020 in FIG. S609 will be described. Also, the layer table 1010 in FIG. 16 shows the state of the layer table 1010 at the time when this processing is performed. Since the check 1023 of the record whose ID 1021 in the check box table 1020 is “5” is “1” indicating check-off, the process proceeds to step S608 by branching to step S606.

  In step S608, the information processing apparatus 101 acquires the parent ID 1022 of the record being processed in the check box table 1020, and acquires from the layer table 1010 the record with the ID 1011 that is the same as the value of the parent ID 1022. Subsequently, the ID 1011 of the record acquired in the layer table 1010 is compared with the reference ID 1013 to determine whether or not they are the same. In this case, when a higher-order component part (assuming to be the second higher-order component part) that is higher than the component part corresponding to the record being processed is checked, the component part being processed and the component part The upper corresponding component is also assigned to the layer of the second upper component. Therefore, it is determined in step S608 to update the reference ID 1013 in step S609. If ID 1011 and reference ID 1013 are the same, the process proceeds to step S604; otherwise, the process proceeds to step S609. If the above example is taken over, the parent ID 1022 of the sixth record is “5”, and the reference ID 1013 is “1” in the record in which the ID 1011 of the layer table 1010 is “5”, so the process proceeds to step S609. It will be.

  In step S609, the information processing apparatus 101 has the same reference ID 1013 stored in the record of the layer table 1010 corresponding to the parent ID 1022 of the record being processed in the check box table 1020 as the ID 1021 of the record being processed in the check box table 1020. Is stored in the reference ID 1013 of the record of ID 1011 of the layer table 1010. That is, the reference ID 1013 of the component corresponding to the upper part of the component of the record being processed is stored in the reference ID 1013 of the component of the record being processed. Taking over the above example, since the parent ID 1022 of the record whose ID 1021 is “6” in the check box table 1020 being processed is “5”, the record acquired in the layer table 1010 is the record whose ID 1011 is “5”. The record reference ID 1013 is “1”. Therefore, the acquired value “1” is stored in the reference ID 1013 of the record whose ID 1011 is “6” in the layer table 1010. The stored result is as shown in a storage example 1601 in FIG. If the process of step S609 is performed, the process proceeds to step S610. Further, for example, the processing is continued as it is, and the result of processing up to the seventh record is as shown in a storage example 1602 shown in FIG. As described above, when the “Unit 01” check box 1401 is checked, the setting is made such that all the components located under the “Unit 01” are assigned to the “Unit 01” layer.

  Next, the outline selection display process will be described with reference to FIG. Note that steps S701 to S708 are performed under the control of the CPU 201 in the information processing apparatus 101.

  A program for causing the information processing apparatus 101 to execute this processing may be prepared as a part of a 3D CAD application installed in the information processing apparatus 101 or as an add-on program. What is a 3D CAD application? It may be prepared as a separately installed program.

  In step S701, the information processing apparatus 101 determines whether the item selected in step S506 is the layer name column 1403. If it is determined that the layer name column 1403 has been selected, the process proceeds to step S702. If not, the process proceeds to step S706.

  In step S702, the information processing apparatus 101 acquires the line number of the display list in the layer name column 1403 selected by the user. For example, when “Structure $ Unit01-1” on the first line is selected, the line number “1” is acquired.

  In step S703, the information processing apparatus 101 acquires a record of ID 1011 corresponding to ID 1021 indicating the same value as the line number acquired in step S702, and acquires a reference ID 1013 of the record.

  In step S704, the information processing apparatus 101 acquires from the layer table 1010 a list of records that store the same reference ID 1013 as the reference ID 1013 acquired in step S703. For example, when the reference ID 1013 acquired in step S703 is “1”, all records having “1” stored in the reference ID 1013 are acquired from all records.

  In step S705, the information processing apparatus 101 acquires the component name 1014 of the record acquired in step S704, and thereby selects a shape contour on the three-dimensional CAD application for all the records acquired in step S704. Do. In this way, on the 3D CAD application after selection, the selected contour line is displayed with a different coloring, so that all assigned to the same layer as the layer name field 1403 received in step S701 are displayed. The contour lines of the components can be visually confirmed.

  In step S706, the information processing apparatus 101 determines whether the item selected in step S506 is the component name column 1402. If it is determined that the component name column 1402 has been selected, the process proceeds to step S707. If not, the contour selection display process ends.

  In step S707, the information processing apparatus 101 acquires the line number of the display list of the component name column 1402 selected by the user. For example, when “Type02.SLDPRT” on the third line is selected, the line number “3” is acquired.

  In step S708, the information processing apparatus 101 acquires a record having the same ID 1011 as the line number acquired in step S707 from the layer table 1010, acquires the component name 1014 of the record, and obtains the shape on the 3D CAD application. A process for selecting a contour is performed. The outline to be selected is displayed as in step S705. The difference from the layer name column 1403 is that when the layer name column 1403 is selected, the outlines of the components belonging to the same layer as that layer are displayed, whereas the component name column 1402 is selected. In this case, only the selected component is displayed. This makes it easier for the user to decide which component to include in which layer.

  Next, the layer creation process will be described with reference to FIG. Note that steps S801 to S806 are performed under the control of the CPU 201 in the information processing apparatus 101.

  A program for causing the information processing apparatus 101 to execute this processing may be prepared as a part of a 3D CAD application installed in the information processing apparatus 101 or as an add-on program. What is a 3D CAD application? It may be prepared as a separately installed program.

  In step S801, the information processing apparatus 101 creates a layer assignment table 1030 based on the layer table 1010, and closes the layer name designation dialog 1400. The layer name 1034 of the layer allocation table 1030 stores the layer name 1016 of the record of ID 1011 having the same value as the reference ID 1013 of the layer table 1010. The values of ID 1011, view name 1012, and component name 1014 of the layer table 1010 are stored in ID 1031, view name 1032 and component name 1033, respectively. The storage result is as shown in FIG. FIG. 17 is a layer allocation table 1030 created based on the storage example 1502 of FIG. Therefore, since “Unit02” is checked, the layer names 1034 whose IDs 1031 of the layer assignment table 1030 are “5”, “6”, and “7” are the same layer.

  In step S802, the information processing apparatus 101 acquires a record of the layer assignment table 1030. Here, an example will be described based on the sixth record.

  In step S803, the information processing apparatus 101 acquires a list of layers already created in step S805 described later. If no layer has been created, it cannot be acquired, so it is not necessary to acquire it as it is.

  In step S804, the information processing apparatus 101 determines whether the layer with the layer name 1034 of the record being processed exists in the list of layers acquired in step S803. That is, it is determined whether or not a layer to which the record being processed is assigned has already been created. If there is a layer with the layer name 1034 of the record being processed, the process proceeds to step S806, and if there is no layer with the layer name 1034 of the record being processed, the process proceeds to step S805. If the above example is taken over, the layer name 1016 with ID 1031 “6” has already been created when the record with ID 1031 “5” is processed, so that an existing layer exists, and the process proceeds to step S806.

  In step S805, the information processing apparatus 101 acquires the value of the layer name 1034 in the layer allocation table 1030, and creates a layer with the name of the acquired value (layer creation unit). For example, the layer name 1034 whose ID 1031 is “5” is “Structure $ Unit01-1 $ Unit02-1”, and thus a layer is created using this layer name 1034.

  In step S806, the information processing apparatus 101 determines whether the record being processed in the layer assignment table 1030 is the last record. If it is determined that the record is the last record, the record creation process is terminated and the process is returned to the caller. If it is determined that the record is not the last record, the process returns to step S802.

  Next, the layer assignment process will be described with reference to FIG. Note that steps S901 to S904 are performed under the control of the CPU 201 in the information processing apparatus 101.

  A program for causing the information processing apparatus 101 to execute this processing may be prepared as a part of a 3D CAD application installed in the information processing apparatus 101 or as an add-on program. What is a 3D CAD application? It may be prepared as a separately installed program.

  In step S901, the information processing apparatus 101 acquires a record from the layer assignment table 1030.

  In step S902, the information processing apparatus 101 selects an outline of drawing data in units of components based on the view name 1032 and the component name 1033 of the layer assignment table 1030 (outline extraction means). For example, when processing is performed for a record whose ID 1031 is “6”, the component name 1033 displayed in “View-1” is selected on the drawing data by selecting a part whose unit name 1033 is “Unit01-1 / Unit02-1 / Type04-1”. Select the contour line. That is, when “View-1” is a front view, an outline on the drawing data when the component name 1033 is “Unit01-1 / Unit02-1 / Type04-1” is viewed from the front is selected. Become. Note that the assembly data is merely data for managing the component data, and is not the three-dimensional model itself, so the processing in steps S902 and S903 may be excluded.

  In step S903, the information processing apparatus 101 assigns the contour line selected in step S902 to a layer that matches the layer name 1034 in the layer assignment table 1030, and identifies and displays each assigned component (layer assignment unit). . For example, taking the above example, if the ID 1031 is “6”, the layer name is assigned to the layer with “Structure $ Unit01-1 $ Unit02-1”.

  When “Unit 02” is checked as shown in the layer name designation dialog 1400 of FIG. 15 and the layer assignment process is performed, assignment is performed as shown in FIG. The layers created in step S805 are “Type 01-1”, “Type 02-1”, “Type 03-1”, and “Unit 02-1”. Components are assigned to each of the four sheets. When the layer assignment processing is performed, “Type01.SLDPRT” is assigned to “Type01-1”, “Type02.SLDPRT” is assigned to “Type02-1,” and “Type03.SLDPRT” is assigned to “Type03-1.” assign. Then, “Type04.SLDPRT” and “Type05.SLDPRT” are collectively assigned to “Unit02-1”. As a result, the outlines of all the components are not assigned to a single layer as shown in FIG. 18 and output, but the outlines of a plurality of components are assigned to a plurality of layers as shown in FIG. Can be assigned separately. Since FIG. 19 is drawing data composed of a plurality of layers, only the component 1901 can be displayed as shown in FIG. By doing this, even a group such as assembly data can be assigned to a layer, and no wasteful work occurs even if it is imported to a two-dimensional CAD application.

  Further, when “Unit 01” is checked and a layer assignment process is performed as in the layer name designation dialog 1400 of FIG. 16, the assignment is performed as shown in FIG. In this case, since the outlines of all the component parts are combined into one layer, “Type01.SLDPRT” to “Type05.SLDPRT” are assigned to “Unit01-1”. That is, it is assigned to a single layer so as to be output by the function of the conventional three-dimensional CAD application. Therefore, an output result as shown in FIG. 18 is obtained.

  In step S904, the information processing apparatus 101 determines whether the record being processed in the layer assignment table 1030 is the last record. If it is determined that the record is the final record, the layer assignment process is terminated and the process is returned to the caller. If it is determined that the record is not the final record, the process returns to step S901.

  As described above, according to the present embodiment, it is possible to assist drawing data output for efficiently performing work with a two-dimensional CAD application using shape data created with a three-dimensional CAD application. For example, FIG. 18 shows drawing data output by assigning the outlines of all components to a single layer, and FIGS. 19 and 20 showing drawing data output by assigning the outlines of components to layers in a unit. Use and compare. In FIG. 18, it is difficult to understand the boundary between the overlapping contour lines, whereas in FIG. 19, since the layer assignment is performed, the display color can be changed for each layer, so it can be confirmed that the boundary between the contour lines is clearer. . Further, since the display / non-display can be changed for each layer, it is possible to further improve the efficiency of the additional operation such as instruction information for the contour line by displaying only a specific layer as shown in FIG.
