  Conventionally, in a database system that manages general design information, one part is registered for each part, and a part drawing file, a part attribute file, and the like generated for each part are managed correspondingly. In this case, since a large number of parts are used to create one product, management becomes very difficult. Thus, in order to efficiently manage the parts constituting the three-dimensional shape model, a method of holding part information in a hierarchical structure using an assembly in which a plurality of parts are combined is currently widely used (for example, Patent Document 1).

(First embodiment)
FIG. 1 is a block diagram showing a configuration of a three-dimensional shape data processing apparatus 100 according to the first embodiment of the present invention. As shown in the figure, the interior of the three-dimensional shape data processing apparatus 100 includes a storage unit 101, a three-dimensional shape data generation unit 102, and a three-dimensional shape data display processing unit 103.

  The three-dimensional shape data generation unit 102 includes a data generation display processing unit 111, a specification unit 112, a search selection unit 113, a component information generation unit 114, a component input processing unit 115, and an integration unit 116. And a component integration file having a plurality of pieces of information of the three-dimensional shape model is generated. The three-dimensional shape data display processing unit 103 includes an integrated input processing unit 121, a specifying unit 122, a development unit 123, a structure generation unit 124, and a component display processing unit 125, and inputs a component integration file. Processing is performed to display the three-dimensional shape model.

  Specifically, in a three-dimensional CAD or the like, a component shape file having information on the shape of a part of the created three-dimensional shape model, and information on coordinates at which two or more components combined as an assembly are arranged. A part configuration file having FIG. 2 is a conceptual diagram conceptually showing the internal structure of the component shape file. As shown in this figure, by having the model name, shape information, and geometric information of a part, the name of the part can be specified when displaying the three-dimensional shape of the part. FIG. 3 is a conceptual diagram conceptually showing the internal configuration of the component configuration file. As shown in the figure, a model name and an arrangement matrix corresponding to the model name are held. The model name held in the part configuration file holds not only the model name of the part but also the model name of the assembly (that is, the assembly in which information on the combination of parts and the coordinates to be arranged is held in another part configuration file). . As a result, the assembly can be held under the assembly, and the parts of the three-dimensional shape model can be held in a hierarchical structure. That is, when the hierarchy in which the assembly exists is used as a reference in this hierarchical structure, each component combined as an assembly exists in a hierarchy below the reference hierarchy. Also, the arrangement information shown in this figure is the arrangement information of parts and assemblies based on the arrangement information of assemblies in the parent hierarchy. As a result, it is possible to specify the location of the part or assembly included in the assembly.

  Then, the three-dimensional shape data generation unit 102 of the three-dimensional shape data processing apparatus 100 according to the present embodiment generates a component integrated file obtained by integrating these files.

  In other words, the part integration file is a file that holds data of a three-dimensional shape model that holds a plurality of parts in a hierarchical structure, and information on the shape of each part included in the three-dimensional shape model in the hierarchical structure (hereinafter, This is a file that holds information on the location of two or more parts or assemblies combined as an assembly (hereinafter referred to as part configuration information) in one file. Also, the component integration file of the present embodiment first arranges the highest component configuration information in the hierarchical structure of the three-dimensional shape model when arranging these component shape information and component configuration information.

  FIG. 4 is a diagram conceptually showing the internal structure of the component integration file. As shown in the figure, it includes part configuration information and part shape information. The component configuration information has an internal configuration as indicated by 401 in the figure, and exists for each assembly included in the three-dimensional model. The component configuration information has the same internal configuration as the component configuration file shown in FIG. On the other hand, the part shape information has an internal configuration as indicated by 402 in FIG. 4 and exists for each part included in the three-dimensional shape model. The component shape information has the same internal configuration as the component shape file shown in FIG. That is, the component integration file has a configuration capable of holding the component shape information and the component configuration information that the plurality of component shape files and the component configuration file have. Then, by arranging the highest level of the hierarchical structure first, it is possible to specify the highest level component configuration information when another device reads the component integration file.

  Further, the present embodiment does not limit the arrangement of the highest-level component configuration information to the beginning of the component integration file, and it may be arranged in a predetermined order. If the order is determined in advance, the top-level component configuration information can be specified when read by another apparatus.

  However, if the information is arranged in a predetermined order instead of the first, the processing becomes complicated because other information needs to be retained in the memory. On the other hand, as shown in the present embodiment, by arranging first, it is possible to easily specify the top-level component configuration information without requiring complicated processing when specifying.

  The storage unit 101 included in the three-dimensional shape data processing apparatus 100 generates a component integration file generated by a three-dimensional shape data generation unit 102 described later and a component integration file generated by the three-dimensional shape data generation unit 102. The component configuration file and the component shape file used in the above are stored. Then, the three-dimensional shape data display processing unit 103 can display the three-dimensional shape model on the monitor 20 using the component integration file stored in the storage unit 101.

  Next, each component provided in the three-dimensional shape data generation unit 102 that generates the component integration file will be described.

  The data generation / display processing unit 111 performs a process of displaying the three-dimensional shape model generated by the user operating the keyboard 10 on the monitor 20. Further, the data generation / display processing unit 111 may generate a three-dimensional shape model using a component shape file and a component configuration file stored in the storage unit 101, or the user operates the keyboard 10. A process of displaying a three-dimensional shape model based on the component information generated in this way may be performed.

  FIG. 5 is an explanatory diagram showing an example of a three-dimensional shape model displayed by the data generation display processing unit 111. As shown in the figure, the 3D shape model to be processed by the 3D shape data processing apparatus 100 of the present embodiment is composed of a plurality of parts, and includes an assembly in which these parts are combined. And Specifically, the assembly 3 is shown as a whole of the displayed three-dimensional shape model, and the combination of the parts 1 and 2 is the assembly 2.

  FIG. 6 is an explanatory diagram showing a hierarchical structure composed of components provided in the three-dimensional shape model shown in FIG. As shown in this figure, assembly 1 exists at the top of the hierarchical structure, assembly 2, part 3, part 4, part 3, and part 4 exist in the lower hierarchy, and further in the layer below assembly 2. Part 1 and part 2 exist. That is, the three-dimensional shape model shown in FIG. 5 is composed of three layers.

  The designation unit 112 designates an assembly that is a target for generating a component integration file for the three-dimensional shape model displayed by the data generation display processing unit 111. Specifically, among the assemblies included in the three-dimensional shape model displayed by the data generation display processing unit 111, the assembly selected by the user with the keyboard 10 is designated. In the example shown in FIG. 5, the assembly 1 and the assembly 2 can be selected as targets for generating the component integration file. In the following description, it is assumed that the user has specified the assembly 1. Further, the specification is not limited to the specification by the user. For example, when there is no specification by the user, an assembly showing the entire three-dimensional shape model displayed on the monitor 20 is set as a generation target of the component integration file. Conceivable.

  The three-dimensional shape data generation unit 102 according to the present embodiment can also select whether or not to generate a component integration file for each assembly included in the assembly specified by the specification unit 112.

  FIG. 7 is a screen that is displayed on the three-dimensional shape data processing apparatus 100, and shows an example of a screen for selecting whether to generate a component integration file for each assembly included in the designated assembly. is there. When the three-dimensional shape data generation unit 102 of the present embodiment generates a component integration file, the screen shown in the figure is displayed on the monitor 20. When the user selects “search all” on the screen shown in this figure, a component integration file is generated for each assembly included in the designated assembly. When the user selects “single unit”, the component integration file is generated only for the designated assembly.

  The search / selection unit 113 searches the hierarchical structure composed of the parts included in the assembly specified by the specifying unit 112, specifies the parts and assemblies included in the specified assembly, and corresponds to the specified parts. The part shape information and the part configuration information corresponding to the identified assembly are selected as information necessary for generating the part integration file. The selected part shape information and part configuration information are information used when the data generation display processing unit 111 displays the three-dimensional shape model. For example, the part shape file and the part input from the storage unit 101 It is assumed that it is generated based on a configuration file or generated as part information by a user.

  FIG. 8 is an explanatory diagram showing an example of a search path for searching for assemblies and parts included in the assembly with respect to the assembly specified by the specifying unit 112. As shown in this figure, the search / selection unit 113 searches along the lines forming the hierarchical structure. Specifically, when the assembly to be searched has an assembly in addition to a part, First, an assembly is set as a search target, and an assembly and a part included in the search target assembly are searched first. Similarly, when the assembly to be searched includes an assembly, the assembly is searched for the lowest layer, and then the parts are searched in order from the lowest layer. Since the parts are searched after the hierarchical structure by the assembly is specified, the assembly and parts included in each assembly can be easily specified. Then, the search / selection unit 113 selects part configuration information and part shape information corresponding to the identified assembly and part as information used when generating the part integration file.

  In addition, when the user selects “search all” on the selection screen shown in FIG. 7, the search / selection unit 113 identifies the parts and assemblies constituting each assembly. FIG. 9 is a diagram showing a list of parts or assemblies provided for each assembly acquired by the search / selection unit 113 searching. That is, when searching according to the search route shown in FIG. 8, the search selection unit 113 first finds the assembly 2 and adds it to the target assembly shown in FIG. Then, the parts 1 and 2 in the lower hierarchy of the assembly 2 are added as configurations of the assembly 1 and the assembly 2. Then, since the part 3 and subsequent parts are configured only by the assembly 1, they are added as the structure of the assembly 1. At this time, the parts already added are not added. For example, a plurality of parts 3 and parts 4 are provided in the assembly 1, but a plurality of parts 3 and 4 are not added to the configuration list of FIG. Then, the search / selection unit 113 selects part configuration information and part shape information corresponding to the assemblies and parts included in the configuration list.

  The part information generation unit 114 generates a part configuration file having the part configuration information selected by the search selection unit 113 and a part shape file having the part shape information. Specifically, the part information generation unit 114 temporarily generates the part configuration information and the part shape information selected by the search selection unit 113 in the storage unit 101 as a part configuration file and a part shape file. In addition, the component information generation unit 114 outputs the generated file name to the component input processing unit 115 and the file name of the component configuration file corresponding to the highest assembly to the integration unit 116.

  FIG. 10 is a diagram illustrating a processed list used when the component information generation unit 114 generates a component configuration file and component shape information. When the component information generation unit 114 generates a component configuration file and a component shape file corresponding to the component configuration information and the component shape information selected by the search selection unit 113, the component configuration information or the component shape information corresponding to the generated file Are sequentially added as a processed list. The component information generation unit 114 confirms the processed list when generating the corresponding file even with the component configuration information or the component shape information selected by the search / selection unit 113, and the corresponding file has already been generated. In this case, it will not be generated. As a result, a file having duplicate contents is not generated, and the size of the component integration file can be reduced. In the drawing, the part configuration information ‘n’ corresponds to the assembly ‘n’, and the part shape information ‘m’ corresponds to the part ‘m’.

  The component input processing unit 115 performs input processing of the component configuration file and the component shape file generated by the component information generation unit 114 and temporarily stored in the storage unit 101, and deletes the input file group from the storage unit 101. .

  In addition, although different from the present embodiment, if the part shape file and the part configuration file are stored in the storage unit in advance, the part input processing unit can input these to generate a component integrated file. is there. Specifically, if the component integration file generation program is "rcc.exe", by entering "rcc.exe (top component configuration file) (output component integration file)" from the command line, A component configuration file that specifies the assembly corresponding to the highest-level component configuration file that is specified as an argument, and the search selection unit configures the lower hierarchy based on the information contained in the highest-level component configuration file The assembly and parts are identified, the part configuration file and the part shape file necessary for generating the part integration file are selected, and the part input processing unit inputs the selected part configuration file and part shape file. Then, the integration unit may generate a component integration file.

  The integration unit 116 generates a component integration file in which the component configuration file and the component shape file input by the component input processing unit 115 are integrated. Specifically, since the file name of the component configuration file indicating the assembly specified by the specifying unit 112 is input from the component information generation unit 114, the integration unit 116 includes the component configuration information included in the component configuration file. Is placed at the beginning of the part integration file, and the part configuration information included in the other part configuration file input thereafter and the part shape information included in the input part shape file are sequentially arranged to integrate the parts. Generate a file. Moreover, there is no restriction | limiting in the arrangement | positioning order of part structure information and part shape information other than the highest-order part structure information. In the present embodiment, the component integration file generated by the integration unit 116 is stored in the storage unit 101.

  FIG. 11 is a diagram illustrating an example of a component integration file generated by the integration unit 116. As shown in this figure, a list of part configuration information and part shape information to be placed in the [Parts Integration File] is held, and after that, part configuration information or part shape information is placed in order. . The first part configuration information is the configuration information of the highest assembly, and the highest level of the hierarchical structure of the three-dimensional shape model is determined. Then, a lower hierarchy can be generated based on the configuration information included in the highest-level component configuration information.

  Further, the arrangement matrix of the configuration information 'm' included in the component configuration information 'n' shown in FIG. 11 is the configuration information 'm' based on the assembly arrangement coordinates indicated by the component configuration information 'n'. The arrangement | positioning coordinate of the assembly or components shown by is shown. In other words, the hierarchical structure is determined, and the uppermost assembly of the hierarchical structure is arranged on the three-dimensional coordinates, so that the arrangement coordinates of all parts and assemblies included in the lower hierarchy are specified. become.

  When “search all” is selected on the selection screen shown in FIG. 7, the integration unit 116 generates a component integration file for each assembly included in the highest assembly. Specifically, the assembly and parts constituting the target assembly can be identified from the configuration list for each assembly created when the search / selection unit 113 searches (in this embodiment, the explanatory diagram shown in FIG. 9). The component integration file can be generated from the component configuration information and the component shape information corresponding to the specified assembly and part. Of course, in the component integration file generated for each assembly, first, component configuration information indicating the highest assembly is arranged.

  The three-dimensional shape data generation unit 102 of the three-dimensional shape data processing apparatus 100 has the above-described configuration, so that a component integration file can be generated from the three-dimensional shape model displayed on the monitor 20.

  Next, each component included in the three-dimensional shape data display processing unit 103 that reads a component integration file and displays a three-dimensional shape model will be described.

  The integrated input processing unit 121 performs input processing of the component integrated file stored in the storage unit 101. The component integration file that is the target of input processing by the integrated input processing unit 121 may be, for example, a component integration file selected by the user by operating the keyboard 10.

  The specifying unit 122 has a hierarchical structure composed of parts included in a three-dimensional shape model to be displayed from the part configuration information placed at the beginning of the part integration file input by the integrated input processing unit 121. Component information, that is, information indicating the highest assembly.

  The expansion unit 123 expands the component configuration information and the part shape information included in the component integration file input and processed by the integrated input processing unit 121 on the storage unit 101 as a component configuration file and a part shape file. These file names may be any file names, but it is preferable to assign file names that can be specified as files corresponding to the component configuration information and the component shape information. In the present embodiment, if it is a part configuration file, “(model name of part configuration information). (Extension indicating the part configuration file)” and “part shape file” (model name of part shape information). (Extension indicating part shape file) ". As a result, the part configuration file and the part shape file can be specified from the configuration information of the part configuration information as shown in FIG.

  The structure generation unit 124 performs an input process on the part configuration file corresponding to the part configuration information specified by the specifying unit 122, and further, the part configuration file and the part corresponding to the model name of the configuration information included in the part configuration file A hierarchical structure of parts and assemblies constituting the three-dimensional shape model is generated by sequentially inputting shape files.

  The component display processing unit 125 performs processing for displaying the three-dimensional shape model on the monitor 20 based on the hierarchical structure of the three-dimensional shape model generated by the structure generation unit 124. That is, the component display processing unit 125 has a hierarchical structure of the three-dimensional shape model generated by the structure generation unit 124, an arrangement coordinate for each component included in the component configuration file, and each component included in the component shape file. A three-dimensional shape model can be displayed by using the shape.

  The three-dimensional shape data display processing unit 103 of the three-dimensional shape data processing apparatus 100 has the above-described configuration, whereby the component integrated file can be input and displayed on the monitor 20.

  The component integration file includes information on a plurality of component shape files and component configuration files, and has a structure that can specify information on the highest component configuration file. As a result, the information of the three-dimensional shape model composed of a plurality of parts can be collected in one file, so that not only the management of the three-dimensional shape model is easy, but also the operation when displaying the three-dimensional shape model becomes easy. .

  More specifically, there are many known methods for archiving a part shape file holding necessary part information and a part configuration file holding necessary part configuration information into one file. For example, there are 'TAR' format and 'ZIP' format. Multiple files can be managed easily by archiving in these formats. However, since the component configuration file indicating the highest level of the hierarchical structure does not hold information for identification, the hierarchical structure of the three-dimensional shape data is restored. It is not possible.

  On the other hand, in the data structure of the component integration file according to the present embodiment, the hierarchical structure can be restored because the highest component can be easily identified by determining that the highest component configuration information is arranged first.

  Next, a processing procedure from displaying a 3D shape model to generating a component integration file in the 3D shape data processing apparatus 100 according to the present embodiment configured as described above will be described. FIG. 12 is a flowchart showing the above-described processing procedure in the three-dimensional shape data processing apparatus 100 according to the present embodiment.

  First, the data generation display processing unit 111 performs a process of displaying the generated three-dimensional shape model on the monitor 20 (step S1201). The designation unit 112 designates an assembly to be generated as a component integration file (step S1202).

  Next, the search / selection unit 113 searches the hierarchical structure composed of the parts provided in the specified assembly, specifies the parts and assemblies provided in the specified assembly, and further specifies the specified parts. Corresponding part shape information and part configuration information corresponding to the specified assembly are selected (step S1203).

  Then, the part information generation unit 114 repeats the processes from step S1204 to step S1210 for all of the selected part configuration information and part shape information.

  The component information generation unit 114 determines whether the component configuration information or the component shape information to be processed is included in the processed list (step S1205). If it is included in the processed list (step S1205: Yes), no particular processing is performed on this part configuration information or part shape information.

  Next, when the component configuration information or the part shape information to be processed is not included in the processed list (step S1205: No), the part information generating unit 114 determines that the processing target is the part information generating unit 114. It is determined whether it is component shape information (step S1206). When it is determined as the component shape information (step S1206: Yes), the component information generation unit 114 generates a component shape file from the component shape information (step S1207).

  If the part information generation unit determines that the part shape information is not part shape information (step S1206: No), since the target information is part configuration information, the part information generation unit 114 obtains a part configuration file from the part configuration information. Generate (step S1208).

  Next, the component information generation unit 114 adds the component shape information or the component configuration information used when generating the file to the processed list (step S1209). Then, since the processing of the part configuration information or the part shape information which is the current processing target is completed, the process starts from step S1204 with the next part configuration information or part shape information as the processing target (step S1210).

  When the processing from step S1204 to step S1210 is completed for all the component configuration information or component shape information, the component input processing unit 115 performs input processing of the generated component configuration file and component shape file (step S1211). ).

  Next, the integration unit 116 integrates the input component configuration file and the component shape file to generate a component integration file (step S1212). Further, when the integration unit 116 generates the component integration file, the integration unit 116 first arranges the component configuration information included in the component configuration file corresponding to the highest-level assembly specified by the specification unit 112 in step S1202, and the like. The part configuration information included in the part configuration file and the part shape information included in the part shape file are arranged thereafter.

  By the processing procedure described above, a component integration file can be generated from the displayed three-dimensional shape model. The processing procedure described above shows an example of the processing procedure from displaying the generated three-dimensional shape model according to the present embodiment to generating the component integration file. It is not limited to.

  Next, a processing procedure from input processing of the component integration file to display processing of the 3D shape model in the 3D shape data processing apparatus 100 according to the present embodiment configured as described above will be described. FIG. 13 is a flowchart showing the above-described processing procedure in the three-dimensional shape data processing apparatus 100 according to the present embodiment.

  First, the integrated input processing unit 121 performs input processing of a component integrated file stored in the storage unit 101 (step S1301).

  Next, the specifying unit 122 specifies the component configuration information arranged at the beginning of the input component integration file as the component configuration information at the top of the hierarchical structure composed of the components provided in the three-dimensional shape model. (Step S1302).

  Then, the expansion unit 123 expands the component configuration information and the part shape information included in the component integration file on the storage unit 101 as a component configuration file and a part shape file (step S1303).

  Next, the structure generation unit 124 sets the part configuration file corresponding to the part configuration information specified in step S1302 as the highest hierarchy, and generates a hierarchical structure from the configuration information included in the part configuration file (step S1302). S1304).

  Then, the structure generation unit 124 determines whether there is a lower hierarchy than the configuration included in the component configuration file (step S1305). Specifically, it is determined whether or not there is a lower hierarchy by determining whether or not the assembly is based on the model name of the configuration information included in the component configuration file.

  When it is determined that there is an assembly, that is, there is a lower hierarchy (step S1305: Yes), the structure generation unit 124 identifies part configuration information corresponding to this assembly (step S1306). In the present embodiment, the structure generation unit 124 specifies information indicating the part configuration information by specifying the model name, and treats it as specifying the part configuration information. If there are a plurality of assemblies in the component configuration file, the component configuration information is specified for each assembly, and the processing described later is performed.

  Next, the structure generation unit 124 sets the corresponding part configuration file based on the identified model name as a hierarchy below the part configuration file that has been processed earlier, and determines the hierarchical structure from the configuration information included in the part configuration file. Is generated (step S1304). Then, it is determined whether or not there is a hierarchy below, and a hierarchical structure is generated (steps S1305 to 1306, step S1304).

  When the hierarchical structure is generated up to the lowest hierarchy (step S1305: No), the component display processing unit 125 performs a process of displaying the three-dimensional shape model based on the generated hierarchical structure (step S1307). .

  According to the processing procedure described above, it is possible to display a three-dimensional shape model after input processing of the component integration file. Note that the processing procedure described above shows an example of the processing procedure from when the parts integration file according to the present embodiment is settled to when the three-dimensional shape model is displayed, and the present invention is limited to this processing procedure. Not what you want.

(Second Embodiment)
In the first embodiment, it has been described that a component integrated file is generated in a single 3D shape data processing apparatus, and that a 3D shape model is displayed by inputting the component integrated file. However, the feature of the component integration file is that the data of the three-dimensional shape model can be held as one file in addition to the one shown in the first embodiment. Therefore, a dedicated component management database that manages information for each component is provided. There is a feature that it can be managed by a general-purpose database (for example, RDBM) without using it. Therefore, in the present embodiment, a three-dimensional shape data management system that manages three-dimensional shape data using a component integration file will be described.

  FIG. 15 is a block diagram illustrating a configuration of a three-dimensional shape data management system according to the second embodiment. The three-dimensional shape data management system according to the present embodiment has a configuration in which a client A 1510 and a server 1520 are connected, and a server 1520 and a client B 1530 are connected. The client A 1510 inputs a part shape file and a part configuration file, generates a part integrated file, transmits it to the server 1520, and registers it in the part integrated file management DB 1525 on the server 1520. When the client B 1530 requests the server 1520 to refer to the three-dimensional shape model, the server 1520 acquires the corresponding component integrated file from the component integrated file management DB 1525 and transmits it to the client B. The received client B 1520 displays the three-dimensional shape model.

  The client A 1510 includes a three-dimensional shape generation program 1511 and a three-dimensional shape registration program 1512. The three-dimensional shape generation program 1511 is a program that performs processing for generating a component integration file from a component shape file and a component configuration file, and the three-dimensional shape data generation unit 102 of the three-dimensional shape data processing apparatus according to the first embodiment. Since the same processing is performed, the description thereof is omitted.

  The three-dimensional shape registration program 1512 includes a DB display processing unit 1513, a communication unit 1514, and a registration specifying unit 1515, and displays the contents of the component integrated file management DB 1525 of the server 1520 to generate a three-dimensional shape. In order to register the component integration file in the record corresponding to the component integration file generated by the program 1511, the component integration file is transmitted to the server 1520.

  The communication unit 1514 receives information of the component integrated file management DB 1525 used when the DB display processing unit 1513 described later displays the contents held in the component integrated file management DB 1525 on the monitor 21, and component integrated file management on the server 1520. When the component integrated file is registered in the DB 1525, the component integrated file is transmitted. In addition, when the communication unit 1514 transmits the component integration file, the communication unit 1514 also transmits information for specifying a record to be registered with the component integration file. In this embodiment, a part number is transmitted as information for specifying a record. Thereby, the server 1520 can register the received component integration file for the corresponding record. Information held by the component integrated file management DB 1525 such as a component number will be described later.

  The DB display processing unit 1513 performs processing for displaying the information of the component integrated file management DB 1525 received from the communication unit 1514 on the monitor 21.

  Then, the registration specifying unit 1515 specifies a record in which the user registers the component integrated file using the keyboard 11 from the information of the component integrated file management DB 1525 displayed on the monitor 21, and further, the component integration corresponding to this record The user specifies the file using the keyboard 11. Then, the registration specifying unit 1515 outputs to the communication unit 1514 that the specified component integration file and the component number indicating the corresponding record are transmitted.

  FIG. 16 is a diagram showing an example of selecting a record to be registered on a screen displayed by the three-dimensional shape registration program 1512. As shown in the figure, for the component classification, the component information managed by the component integrated file management DB 1525 of the server 1520 is displayed in a hierarchy according to the classification, and the component list includes the records held by the component integrated file management DB 1525. Displays information for each field.

  The user selects a record displayed in the parts list using the keyboard 11 and right-clicks to display a selection window 1601. Then, by selecting an integrated file from the selection window 1601, an integrated file window 1602 is displayed. When “Register” is selected from the displayed integrated file window 1602, the file window 1701 shown in FIG. 17 is displayed.

  FIG. 17 is a diagram showing an example in which a corresponding component integration file is selected after specifying a record to be registered on a screen displayed by the three-dimensional shape registration program 1512. As shown in the figure, by selecting a component integration file corresponding to the specified record from the file window 1701 and pressing an “Open” button 1702, the component integration file to be transmitted is specified. Then, the communication unit 1514 can transmit the part number and the part integration file of the specified record.

  The server 1520 includes a three-dimensional shape data management program 1521 and a component integrated file management DB 1525. In response to a request from another client, the information held by the component integrated file management DB 1525 and the transmission of the component integrated file are transmitted.

In addition, the communication unit 1523 receives a component number corresponding to the component integration file from another client and outputs the received component number to the registration unit 1522.

  The reference request unit 1524 acquires information held in the component integrated file management DB 1525 in response to a request from another client, and outputs the acquired information to the communication unit 1523. In addition, when a condition is set for information acquired by another client, the reference request unit 1524 searches the component integrated file management DB 1525 with the set condition, and satisfies the condition set by the search. It is also possible to acquire only the information and output it to the communication unit 1523. It is conceivable that the condition to be acquired is set when, for example, a condition for referring to a reference request from another client is set. Further, when a request for referring to the component integrated file together with the component number is input from the communication unit 1523 from another client, the reference request unit 1524 acquires the file name from the component integrated file management DB 1525 using the component number as a key. The component integration file specified by the above is output to the communication unit 1523. As a result, other clients can acquire and display the component integration file.

  The registration unit 1522 receives the component integration file and the component number from the communication unit 1523, identifies the record to be updated in the component integration file from the input component number, and uses the file name of the received component integration file as a field. Update “file name” and field “file existence” to “1”. As a result, the component integration file is registered in the component integration file DB 1525.

  Then, the registration unit 1522 performs processing so as to hold the received component integrated file on the server. As a result, the registration of the received component integrated file is completed, and the server 1520 can transmit the component integrated file corresponding to the record of the component integrated file management DB 1525.

  The client B 1530 includes a three-dimensional shape display program 1531.

The component integration file used when displaying the three-dimensional shape model is received.

  The DB display processing unit 1533 performs processing for displaying the information of the component integrated file management DB 1525 received from the communication unit 1532 on the monitor 22.

  Then, the component display processing unit 1534 performs processing for displaying a three-dimensional shape model from the component integration file input from the communication unit 1532. Further, the processing from displaying the part integration file to displaying the 3D shape model is the same as the processing performed by the 3D shape data display processing unit 103 provided in the 3D shape data processing apparatus 100 of the first embodiment. Therefore, explanation is omitted.

  FIG. 19 is a diagram showing an example of selecting a record to be displayed on a screen displayed by the three-dimensional shape display program 1531. In this figure, as in FIG. 16, for component classification, the component information managed by the component integrated file management DB 1525 of the server 1520 is displayed in a hierarchy according to the classification, and the component integrated file management DB 1525 is displayed for the component list. Displays information for each field of the record to be retained.

  The user selects a record displayed in the component list using the keyboard 11 and right-clicks to display a selection window 1901. Then, by selecting an integrated file from the selection window 1901, an integrated file window 1902 is displayed. When “reference” is selected from the displayed integrated file window 1902, the three-dimensional shape model shown in FIG. 20 is displayed on the monitor 22.

  FIG. 20 is a diagram illustrating an example in which a corresponding three-dimensional shape model is displayed by specifying a record to be registered on a screen displayed by the three-dimensional shape display program 1531. As shown in the figure, the corresponding three-dimensional shape model is displayed as a separate window 2001. Then, a tree display of the components constituting the displayed 3D shape model is displayed in 2002, and the 3D shape of the 3D shape model associated with the record selected in the screen example shown in FIG. 19 is displayed in 2003. indicate.

  Specifically, by selecting “reference” of the integrated file for a specific record in FIG. 19, the communication unit 1532 transmits to the server 1520 together with the component number that the component integrated file is transmitted. When the communication unit 1523 of the server 1520 receives information indicating that the component integrated file is to be transmitted, the reference request unit 1524 identifies the file name of the 3D shape model from the component integrated file management DB 1525 with the component number. Then, the communication unit 1523 transmits the identified component integration file to the transmission source client. When the communication unit 1523 of the client B 1530 receives the component integration file, the component display processing unit 1534 performs processing for displaying the three-dimensional shape model from the component integration file on the monitor 22.

  With the above-described configuration, the client B 1530 can display the three-dimensional shape model for the part that has made a reference request.

  In the component integrated file management DB 1525, only “file presence / absence” and “file name” are held as information of the component integrated file, but it is not limited to holding only these. For example, it is conceivable to manage binary information of a component integration file as field information.
