<First Embodiment>
Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.

  First, an example of the configuration of an information processing system in the embodiment of the present invention will be described with reference to FIG.

  The information processing system of the present invention is configured such that a PC 100 and a server 200 are communicably connected via a LAN 101 (local area network).

  The PC 100 is installed with CAD software and an interference check pattern specifying tool (interference check pattern specifying software) that functions as an add-on to the CAD software.

  The PC 100 and the server 200 store data (an assembly file, a part file, etc.) of a three-dimensional model generated by CAD software (CAD software).

  An assembly is one of CAD files (a 3D model file in 3D CAD). An assembly (design data) refers to a plurality of parts (file storing the shape of the three-dimensional model / extension is prt), and a three-dimensional model combining a plurality of referenced parts (component parts) It is a file to display. In the assembly, the file name of the referenced part, the storage location, the position / posture in the three-dimensional space of the three-dimensional CAD, and the information on the matching of the parts are stored. The extension of the assembly file is asm or sldasm.

  “Match” is restriction information that restricts the movement of entities (elements in design data such as points, surfaces, and edges) in design data. For example, it is information for fixing the relative positions of target entities or limiting the distance between entities. Details of the match will be described later in the description of 600 in FIG.

  In the present embodiment, an assembly for which a user desires an interference check is described as an interference check target assembly. For example, an assembly developed in a window (CAD software window) instructed to start the interference check pattern specifying tool is set as an interference check target assembly.

  The interference check pattern is information for performing an interference check, and is information that defines which entity (which component has which entity) and how to drive it. The interference check pattern file in the present embodiment is a master assembly file to be described later.

  An entity is a generic term for elements in design data, such as points, faces, and edges.

  The master assembly is an assembly file that stores which entities (parts having entities) and how to drive them, and is stored in advance in the external memory of the server 200. The above is the description of FIG.

  Hereinafter, an example of a hardware configuration of various apparatuses according to the embodiment of the present invention will be described with reference to FIG.

  In FIG. 2, reference numeral 201 denotes 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 BIOS (Basic Input / Output System) or an operating system program (hereinafter referred to as an OS), which is a control program of the CPU 201, or a function executed by each server or each PC. Various programs to be described later are stored.

  A RAM 203 functions as a main memory, work area, and the like for the CPU 201. The CPU 201 implements various operations by loading a program or the like necessary for execution of processing from the ROM 202 or the external memory 211 into the RAM 203 and executing the loaded program.

  An input controller 205 controls input from a keyboard (KB) 209 or a pointing device such as a mouse (not shown). A video controller 206 controls display on a display device such as a CRT display (CRT) 210. In FIG. 2, although described as CRT 210, the display device is not limited to the CRT, but may be another display device such as a liquid crystal display. These are used by the administrator as needed.

  A memory controller 207 is connected to the hard disk (HD), flexible disk (FD), or PCMCIA card slot for storing a boot program, various applications, font data, user files, editing files, various data, etc. via an adapter. The access to the external memory 211 such as a compact flash (registered trademark) memory is controlled.

  A communication I / F controller 208 is connected to and communicates with an external device via a network (for example, the LAN 101 shown in FIG. 1), and executes communication control processing on the network. For example, communication using TCP / IP is possible.

  Note that the CPU 201 enables display on the CRT 210 by executing outline font rasterization processing on a display information area in the RAM 203, for example. In addition, the CPU 201 enables a user instruction with a mouse cursor (not shown) on the CRT 210.

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

  Next, an example of the functional configuration of the functional configuration according to the embodiment of the present invention will be described with reference to FIG.

  The assembly acquisition unit 311 is an acquisition unit that acquires an assembly file from the external memory of the PC 100 or the external memory of the server 200. The assembly development unit 312 performs processing for opening the assembly acquired by the assembly acquisition unit 311 on CAD software.

  The match processing unit 313 performs processing for matching entities in accordance with a user operation or an instruction from the interference check pattern specifying tool. That is, the restriction information is added to the target element.

  The interference determination unit 314 performs an interference check (determination) to check whether components are interfering with each other, and outputs and stores the result of the interference check on the memory.

  The interference check pattern storage unit 321 stores interference check pattern information. That is, it is a storage unit for storing the master assembly file. The interference check pattern specifying condition storage unit 322 is a storage unit that stores information on conditions (for example, 630 in FIG. 6) for specifying an interference check pattern applicable to an assembly being developed by CAD software.

  The interference check pattern specifying condition transmission unit 323 transmits an interference check pattern specifying condition to the PC 100 in response to a request from the PC 100. The interference check pattern specifying condition acquisition unit 315 receives and acquires the interference check pattern specifying condition and stores it in the memory.

  The interference check pattern specifying unit 316 specifies an interference check pattern that can be applied to the assembly being developed using the match in the assembly being developed and the match indicated by the interference check pattern specifying condition.

  The interference check pattern acquisition unit 317 requests the server 200 for information on the interference check pattern specified by the interference check pattern specification unit 316. The interference check pattern transmission unit 324 acquires information of the requested interference check pattern from the interference check pattern storage unit 321 and transmits it to the PC 100, and the interference check pattern acquisition unit 317 acquires this and stores it in the memory.

  The entity match control unit 318 refers to the inside of the interference check pattern information acquired by the interference check pattern acquisition unit 317 and identifies a matching entity included in the interference check pattern. Then, the entity specified from the interference check pattern and the entity in the assembly under development corresponding to the entity are specified and controlled to match. For example, the matching processing unit 313 included in the CAD software is instructed to match the entity specified from the interference check pattern with the entity in the assembly being developed corresponding to the entity.

  The interference check execution control unit 319 reads the drive information included in the information of the interference check pattern, and controls to perform the interference check when the components in the assembly being developed move according to the drive information. For example, the CAD software is instructed to move the entity (part including the entity) according to the driving information, and the interference determination unit 314 is instructed to perform an interference check while moving. The above is the description of FIG.

  Hereinafter, it is assumed that the CPU 201 of the PC 100 or the server 200 executes the processing of each step of each flowchart described using the function of software installed in the own device.

  Next, with reference to FIG. 4, an outline of processing in the embodiment of the present invention will be described.

  In step S401, the CAD software is activated by a user operation, and the assembly selected by the user is expanded on the CAD software (corresponding to a designation receiving unit). For example, a CAD screen 700 in FIG. 7 is displayed.

  An example of the assembly is shown in TopAssy of FIG. TopAssy1 is an assembly file including assembly information 1100 and matching information 600.

  Record No. 1101 is an identification number in the assembly of the file referred to by the assembly. Level 1102 stores the configuration hierarchy of each file. The folder path 1103 stores the folder path of each file.

  The file name 1104 stores the file name of each file that TopAssy itself and TopAssy refer to directly or indirectly.

  In the configuration path 1105, a reference-related path in a general three-dimensional CAD is registered. For example, a value of Null is registered as the value of the configuration path 1105 located at the top of the file structure (configuration).

  The configuration path of Assy1, which is a file directly referenced by TopAssy, is TopAssy. That is, Assy1 is directly referred to TopAssy.

  Furthermore, the configuration path of the file Part1 that TopAssy indirectly refers to via Assy1 is TopAssy / Assy1. That is, Part1 is directly referred to Assy1 and indirectly referred to TopAssy.

  The type 1106 stores the type of processing file. The type is distinguished by the extension of the CAD file.

  In addition, elements such as surfaces, lines, and points generated in the file are stored in the assembly file and the part file, and are expressed by XYZ coordinates and XYZ in the three-dimensional space of the element. Information on the angle is stored. The match information 600 will be described later.

  In step S402, the CAD software executes an activation command for the interference check pattern identification tool by a user operation, and the interference check pattern identification tool is activated in step S403 according to the command. The activated interference check pattern specifying tool specifies (determines) an assembly developed in the active window of the CAD software as an assembly to be checked for interference, and stores identification information (eg, file name) of the assembly in a memory.

  In step S404, the interference check pattern specifying tool executes an interference check pattern specifying process (master assembly specifying process). The master assembly determination process will be described later with reference to FIG.

  Here, with reference to FIG. 5, the flow of the master assembly specifying process will be described.

  In step S501, the interference check pattern identification tool requests the CAD software for a list of matching information of the assembly being developed, acquires the list of matching information from the CAD software, and stores it in the memory. An example of the match information list is shown at 600 in FIG. The match information 600 is a list of all match information included in the interference check target assembly opened by the CAD software.

  The match name 601 is a match display name and is match identification information. A type 602 is a type (type) of matching. Match types include, for example, match (matches that match vertices (points), edges (lines / axes), and faces (planes)), distance restrictions (relative distances that specify the relative distance between lines, faces, etc.) , Constrain circles (matches that match the centers of multiple circles, cylinders, points, spheres, etc.), lock (Match that completely fixes the relative position between multiple entities).

  The matching entity A 603 and the matching entity B 604 are entities (generic names of elements such as points, faces, edges, and the like) that are targets of matching.

  The restriction 605 is information indicating a relative distance or / and a relative angle range that can be moved / changed between the matching entity A and the matching entity B. In the case of an angle 1 of 600, the angle between the entity A and the entity B can be changed only between X1 ° and X2 °. For example, when X1 ° = 0 ° and X2 ° = 30 °, the angle between the matching entity A and the matching entity B cannot be −1 ° or less and 31 ° or more.

  In step S <b> 502, the interference check pattern identification tool requests acquisition of all the narrowing match information stored in the server 200. The narrowing match information is a match narrowing condition that is necessary for the interference check and may be used for the interference check. An example of the narrowing match information 610 is shown at 610 in FIG. The narrowing match information 610 is stored in advance on the server 200, and the match information of all master assemblies stored on the server 200 is stored.

  Since the type 612, the matching entity A 614, and the matching entity B 615 are the same as the type 602, the matching entity A 603, and the matching entity B 604, respectively, description thereof is omitted.

  The match code 611 is identification information (ID) of a combination (match condition) of the type 612, the match entity A 614, and the match entity B 615.

  The drive information name 613 is identification information of drive information applicable to a combination of the type 612, the matching entity A 614, and the matching entity B 615 (a match that satisfies the conditions of the type and the combination of entities).

  The drive information is stored in the master assembly. The master assembly has matching information having the same configuration as the matching information described in 600. Also, it has drive information as indicated by reference numeral 650 in FIG.

  The drive information name 651 is the name of each drive information. Each driving information includes a component including which entity (driving entity) in the master assembly, in which direction (driving direction 653) of the X, Y, and Z directions, and what angle and / or distance (driving angle / driving). This information stores information about whether to drive the component so as to change the relative angle and / or relative distance between the driving entity and another entity that matches the driving entity by the distance 654).

  According to the drive information 650 in FIG. 6, the surface element named surface 1 in the part file named Part1 referred to by the interference check target assembly is X1 ° in the X direction according to the record of “matching entity: Part1: surface 1”. Drive in the range of ~ X2 °.

  Further, according to the record of “matching entity: Part 1: cylindrical surface 1: XYZ”, a point at a position separated by XYZ from the center of gravity position of the cylindrical surface element called surface 1 in the part file called Part 1 referenced by the assembly to be checked for interference Are driven in the range of X1 ° to X2 ° in the directions of XYZ.

  An example of the master assembly is shown in master assembly A in FIG. Descriptions of 1111 to 1118 of the assembly information 1110 are the same as 1101 to 1108, respectively, and thus description thereof is omitted. Further, explanations of 1121 to 1125 of the match information 1120 are the same as 601 to 605 of the match information 600, respectively, and thus description thereof is omitted.

  Returning to the description of FIG. In step S503, the server 200 receives the narrowing match information acquisition request. In step S504, the server 200 acquires narrowing match information 610 stored in the memory of the own device, and the PC 100 (interference check pattern specifying tool). Send to.

  In step S505, the interference check pattern specifying tool receives the narrowing match information 610 and stores it in the memory.

  In step S506, the interference check pattern identification tool compares the match information 600 on the memory with the match information for narrowing 610, and the type 602, the matching entity A 603, and the matching entity B 604 are all the type 612, the matching entity A 614, and the matching. Records that respectively match the entity B 615 are specified and stored in the memory as interference check match information 620. That is, the matching information that can be used for the interference check in the interference check target assembly is specified.

  In the entity matching determination, even if the names of the entities are different, if the entity types (plane, point, line, etc.) are the same, they are regarded as matching.

  In step S507, the interference check pattern specifying tool displays an interference check pattern display screen 710 (interference check pattern selection screen) as shown in FIG. 7 on the display screen, and the match information 620 for interference check is displayed on the list display unit 712. Display a list of The drive information selection unit 715 is a display unit that can display and select the drive information name 624 (can accept a selection operation). In addition, the file name of the interference check target assembly is displayed in 711.

  In step S <b> 508, the interference check pattern specifying tool transmits an acquisition request for the interference check pattern specifying condition 630, which is a condition for specifying an interference check pattern (master assembly) executable in the interference check target assembly, to the server 200.

  The match code 631 is identification information of a match type (612) and a combination (match condition) of match entities (641, 615) to which the match is applied.

  The interference check pattern 632 is a list of names of interference check patterns (master assemblies), and is a table that stores which matching conditions are necessary for performing interference checks for each interference check pattern.

  In this embodiment, it is assumed that the matching condition of the matching code in which the value “1” is inserted is necessary. For example, when only the match codes = AE001 and AE002 exist in the interference check match information 620 (that is, when the match conditions are AE001 and AE002), the interference check pattern of the interference check A is used as the interference check target assembly. It is applicable to.

  The interference check pattern in the embodiment of the present invention is a master assembly. The master assembly includes drive information (operation information indicating how much the matched entity (part containing the entity) is moved).

  The driving range is limited to a limit 655 or a limit 605 range. When the interference check is actually performed, the drivable range is determined according to a smaller limit value among each limit 655 and each limit 605 of the interference check target assembly to which the master assembly (interference check pattern) is applied.

  Further, for example, when the part of entity A is moved and the angle between entity A and entity B is opened to 30 °, the limit 655 or limit 605 of the same part or another part whose operation is interlocked with the part is exceeded. In this case, the angle between the entity A and the entity B can be changed up to 29 °.

  By matching (fixing) the entity in the master assembly with the entity in the interference check target assembly and then driving the master assembly part (according to the driving information), the interference check target assembly The component also moves (drives) in the same direction by the same angle and distance. An example of driving is shown in FIG.

  In step S509, the server 200 receives an acquisition request for the interference check pattern specifying condition 630, and in step S510, transmits the interference check pattern specifying condition 630 stored in the external memory of the own device to the PC 100 (interference check pattern specifying tool). To do.

  In step S511, the interference check pattern specifying tool receives the interference check pattern specifying condition 630 and stores it in the memory.

  In step S512, the interference check pattern identification tool identifies an interference check pattern applicable to the interference check target assembly being developed.

  Specifically, the match code 621 of the interference check match information 620 is referenced, and the match code (“1”) necessary for applying the interference pattern indicated by 632 is inserted into the interference check match information 620. It is determined for each interference pattern whether all the matching codes 631) exist.

  The interference check pattern specifying tool generates an interference check pattern list 640 on the memory. Then, the interference check name 641 is inserted into the interference check pattern name 641 with the name of the interference pattern determined to include all the matching codes necessary for applying the interference pattern indicated by 632 in the interference check match information 620. Store as 642 = 0 record.

  Also, the interference check pattern name 641 is inserted into the interference check pattern name 641 in the interference check match information 620, the interference pattern name determined to be part or all of the matching code required to apply the interference pattern shown in 632, The number of matching conditions that are insufficient (number of insufficient matching conditions) is specified, and the specified number is inserted into the number of insufficient matching conditions 642 and stored.

  The number of insufficient matching conditions = 0 means that the condition for applying the interference check pattern is satisfied, and the target of the driving operation registered in the interference check pattern (master assembly) is displayed on the assembly being developed. All of the entities that exist. That is, the interference check pattern with the number of insufficient matching conditions = 0 is an interference check pattern applicable to the assembly being developed.

  On the other hand, the fact that the number of matching conditions is insufficient means that there is a shortage of entities that are the targets of the driving operation registered in the interference check pattern (master assembly). In other words, the open assembly cannot perform the driving operation registered in the interference check pattern (master assembly) in which the number of matching conditions is insufficient. That is, an interference check pattern with insufficient number of matching conditions cannot be applied to the assembly being developed.

  In step S513, the interference check pattern specifying tool displays the interference check pattern list 640 (master assembly list) on the display screen. For example, it is displayed on the master assembly list display section 713 (interference check pattern identification information list) in FIG.

  Thereby, the interference check pattern applicable to the design data (assembly) under development can be presented to the user.

  Further, in the present embodiment, a master assembly with the number of insufficient matches = 0 is displayed so as to be selectable, and is grayed out so that a master assembly with the number of insufficient matches = 1 or more cannot be selected.

  This allows the user to easily check whether a desired interference check pattern can be applied to the assembly being developed.

  In step S514, the interference check pattern specifying tool accepts a selection of an interference check pattern (master assembly) to be applied to the assembly under development from the master assembly list displayed in the master assembly list display unit 713 (in the selection accepting unit). Applicable).

  The interference check pattern specifying tool specifies the drive information 650 in the selected master assembly, and displays it on the drive information selection unit 715 so that only the drive information name 651 of the specified drive information 650 can be selected (drive information). The display of the selection unit 715 is updated). Further, for a match to which none of the drive information in the selected master assembly can be applied, control is performed so that the list display unit 712 does not display it, and the display of the list display unit 712 is updated (match information list display means) Fall under).

  For example, when a master assembly is selected in 713, drive information 650 in the master assembly is specified, and each drive information name in the drive information 650 is replaced with a drive information selection section in the matching information corresponding to each drive information. 715 is displayed. In other words, in accordance with the selection of the master assembly, drive information to be applied to each match (component element whose movement is restricted by the match) is automatically selected.

  In step S515, the interference check pattern specifying tool accepts pressing of the “execute” button 714, and in step S516, determines (specifies) an interference check pattern (master assembly) to be applied to the assembly being developed. In addition, the drive information selected by the drive information selection unit 715 is determined as drive information to be applied to each matching entity (part including the entity), and the processing in FIG. 5 ends.

  When the interference check pattern specifying tool detects that the match information in the assembly being developed has been added, deleted, or the match condition of the existing match information has been changed by a user operation on the CAD software window, The interference check pattern specifying tool executes steps S501 to S513 to update the display of 712 and 713 in FIG.

  Returning to the description of FIG. In step S405, the interference check pattern specifying tool instructs the CAD software to expand the master assembly selected when the “execute” button 714 is pressed.

  In step S406, the CAD software accepts the instruction, reads the master assembly instructed in step S407 from the external memory of the server 200, and expands it. An example of a developed master assembly is shown at 800 in FIG. At this time, the interference check target assembly and the master assembly are simultaneously developed on the CAD software as indicated by 700 and 800.

  When the interference check pattern specifying tool detects that the development process has been completed using the API function of the CAD software, in step S408, the interference check target assembly being developed on the master assembly developed for the CAD software. Is inserted as a part (component) referred to by the master assembly.

  The CAD software that has received the instruction in step S409 inserts the instructed interference check target assembly as a component on the master assembly instructed in step S410.

  When the interference check pattern specifying tool detects that the insertion process is completed using the API function of the CAD software, in step S411, the interference check pattern specifying tool instructs execution of matching according to the master assembly (corresponding to the position control means). The match indicated here is a type of “match” that fixes the relative positions of a plurality of elements (component elements).

  Specifically, the interference check pattern specifying tool acquires the matching code 631 (for example, AE0001 and AE0002 for the interference check E) necessary for applying the interference check pattern of the master assembly, and these matching codes indicate It is instructed to match (fix) the matching entity A 614 and the matching entity B 615 on the master assembly and the matching entity 622 and the matching entity 623 of the matching code 621 on the interference check target assembly.

  For example, the surface inside the hole (cylinder) of the part 1001 in the assembly to be checked for interference as indicated by 1000 and 1010 in FIG. 10 (matching entity A 603 / example: “Part 1: cylindrical surface 1” in 603 in FIG. 6); Instruct to match the cylindrical inner surface of part 1012 in the master assembly (matching entity A 614 / example: “Part1: cylindrical surface 1” in 1123 of FIG. 11). Further, the outer surface of the cylinder of the part 1002 (matching entity B604 / example: “Part3: cylindrical surface 1” in 604 of FIG. 6) and the outer surface of the cylinder of the part 1012 (matching entity B615 / example: FIG. 11) 1Part 12: “Part2: Cylindrical surface 1”).

  1020 and 1030 in FIG. 10, the plane of the part 1001 (matching entity A 603 / example: “Part 1: plane 1” in 603 in FIG. 6) in the assembly to be checked for interference, and the part 1011 in the master assembly An instruction is given to match the plane (matching entity A 614 / example: “Part1: plane 1” in 1123 of FIG. 11). Also, the plane of the part 1013 in the assembly to be checked for interference (matching entity B604 / example: “Part3: plane 3” in 604 in FIG. 6) and the plane in the master assembly (matching entity B615 / example: 1124 in FIG. 11). "Part2: Surface 3") is matched.

  In step S412, the CAD software accepts the instruction, and in step S413, in accordance with the instruction, the matching entity A614 and the matching entity B615 of the specified matching code 631 on the master assembly and the matching code 631 on the interference check target assembly according to the instruction. The matching entity 622 and the matching entity 623 having the same match code 621 are matched, and the relative positions of the matched entities are fixed. In other words, the type of “match” is applied.

  When the interference check pattern identification tool detects that the matching process is completed using the API function of the CAD software, in step S414, the driving information registered in the master assembly that has performed the matching process for the CAD software. Among them, the parts for which each match is set (parts including the entity for which each match is set) are operated according to the drive information selected by the drive information selection unit 715 when the “execute” button 714 is pressed, and the interference check is performed. Is executed (corresponding to drive control means).

  Thereby, in conjunction with the movement of the entity of the master assembly according to the drive information registered in the master assembly, the entity (part including the entity) in the interference check target assembly that matches the entity can be moved. .

  Therefore, the interference check can be performed with the movement registered in the master assembly.

  In step S415, the CAD software accepts the instruction. In step S416, the CAD software executes the interference check function of the CAD software itself in accordance with the received instruction, and automatically performs the interference check process by driving the component. That is, the coordinates (X, Y, Z) at which the part interferes with another part during driving of the part, the date and time of interference, and the identification information of the other part that interfered are displayed and recorded as a result of the interference check. Process.

  In the interference check pattern display screen 710, a drive information selection unit 715 is displayed in each row. When “Do not apply drive information” is selected in the drive information selection unit 715, for the matching entity for which “Do not apply drive information” is selected, the CAD software is not instructed to drive. . It is assumed that only an instruction to drive a matching entity for which drive information to be applied is selected by the drive information selection unit 715 is transmitted to the CAD software.

  As a result, the user can drive an arbitrary matching entity (part including the entity) to perform an interference check.

  Further, in the interference check pattern display screen 710, when there are a plurality of drive information applicable to one matching condition, the driving information selection unit 715 of the matching row that satisfies the matching condition becomes a target of the matching. The drive information to be applied to the existing entity is displayed in a selectable manner. When the “execute” button 714 is pressed, the CAD software is instructed to drive the matching entity according to the drive information selected by the drive information selection unit 715.

  As a result, the user can perform the interference check by operating the component according to the arbitrary drive information.

  As described above, according to the present invention, it is possible to provide a mechanism capable of easily performing an interference check to be performed on a target model.

<Second Embodiment>
Hereinafter, a second embodiment of the present invention will be described.

  There are times when you want to perform an interference check for parts that have not yet been checked for interference.

  Even if a component has already been checked for interference, it may be desired to redo the interference check when the interference check is performed by an inappropriate driving method.

  The second embodiment of the present invention aims to provide a mechanism that can easily specify a driving method of a part related to restriction information on a design based on driving results.

  Hereinafter, the second embodiment will be described with reference to FIGS. 12 and 13.

  The process in FIG. 12 starts after step S512 in FIG. In step S <b> 1201, the interference check pattern identification tool acquires information on the driving performance (illustrated by 1320 in FIG. 13) corresponding to the interference check target assembly from the external memory 211.

  The drive record 1320 is generated and stored by the interference check pattern specifying tool after step S414 in FIG.

  Specifically, the match name 1321 of the match that is the target of the interference check execution instruction is stored. Also, the date and time 1324 when the execution instruction is given is stored.

  Further, the drive information name 1323 for driving the part set with the match is stored, and the identification information of the master assembly (the interference check pattern selected in 713 in FIG. 7) including the drive information of the drive information name 1323 is stored. Stored as an application pattern 1322. That is, a record of which drive information of which master assembly is applied to which match (part to which which match is set) is stored.

  Returning to the description of FIG. In step S1202, the interference check pattern identification tool determines whether the drive record 1320 has been acquired by the acquisition process of step S1201.

  That is, it is determined whether or not the interference check target assembly has a past record of performing interference check based on the master assembly.

  If the drive record 1320 has been acquired, the process proceeds to step S1203. If not acquired, the process proceeds to step S513 in FIG.

  In step S1203, the interference check pattern specifying tool specifies a match having no drive record by the master assembly (drive record by the drive information of the master assembly) from the match information (match information for interference check).

  For example, when the interference check target assembly is TopAssy in FIG. 13, TopAssy has the match information 1300, the interference check match information is 1310, and the TopAssy drive record 1320 is acquired, step S <b> 1203. The match information specified by is a record of match code = AE000X.

  The items of the match information 1300 and the interference check match information 1310 are the same as the match information 600 and the interference check match information 620 of FIG.

  In step S1204, the interference check pattern specifying tool displays interference check match information 1310 and interference check pattern (master assembly) identification information together with drive performance information. Specifically, a screen such as an interference check pattern display screen 1400 in FIG. 14 is displayed.

  In the interference check pattern display screen 1400, information on whether there is a record of driving using the master assembly, that is, whether there is a record of interference check, for which match in 1411 (for which match is set). Based on the drive record 1320, a “pattern” indicating the name of a certain “actual record”, a master assembly (interference check pattern) having a record record, and a “drive information name (actual record)” that is a drive information name actually used for driving. indicate.

  In 1402, the master assembly (interference check pattern) that has been applied to the interference check target assembly, that is, the “actual” item of the master assembly corresponding to the drive information applied to the interference check target assembly is “present”. "Is displayed.

  The interference check pattern specifying tool shifts the processing to step S514 in FIG. 5 and ends the processing in FIG.

  As described above, in the second embodiment of the present invention, it is possible to confirm parts that have not yet been checked for interference. Also, it is possible to confirm parts that have already been checked for interference.

  That is, it is possible to provide a mechanism that can easily specify a method of driving a component related to the restriction information of the design based on the driving performance.

  In the description of the second embodiment, the results are stored and registered according to the interference check execution instruction. For example, the interference check pattern specifying tool monitors the operation of the CAD software and actually implements the interference check function. When it is detected that the component has been driven, the driving record 1320 may be stored in the external memory.

  Further, as shown in 1500 of FIG. 15, when a check box 1503 is provided on the interference check pattern display screen, and the operation for checking the 1503 is performed, the interference check pattern specifying tool displays the matching information for the interference check with a driving record. Then, the interference check pattern that has been applied to the interference check target assembly and the interference check pattern that cannot be applied are hidden in 1501 and 1502, so that it is possible to easily confirm parts and interference check patterns that have not yet been checked for interference. It may be.

  That is, only the interference check matching information that has not been driven by the master assembly may be displayed in a selectable manner.

  Further, only the master assembly that has not been applied to the interference check target assembly may be displayed in a selectable manner.

  When an operation for removing the check is accepted, the screen returns to the screen on which the interference check match information and the interference check pattern that have been hidden are displayed.

  Further, as shown by 1510 in FIG. 15, identification information (1511) for matching information for interference check with no record is identified and displayed (1512) for an interference check pattern with no record applied to the interference check target assembly. It may be possible to easily confirm a part that has not been checked for interference or an interference check pattern.

<Third Embodiment>
Hereinafter, a third embodiment of the present invention will be described.

  There are times when you want to perform an interference check for parts that have not yet been checked for interference.

  When there are multiple master information (interference check pattern) with applicable match (limitation information) or drive information applicable to drive information, it is troublesome to find information that has not yet been checked for interference from the multiple information . For example, when the number of pieces of information displayed on the list is large, information that has not been checked for interference must be searched by scrolling the list.

  The third embodiment of the present invention aims to provide a mechanism that can easily specify a driving method of a part related to restriction information of a design object by changing the display priority based on the driving performance. To do.

  For example, immediately after step S1203, the interference check pattern specifying tool rearranges the interference check match information 1310 so that a record without a drive record is higher than a record with a drive record. That is, priority is given to information without a driving record over information with a driving record.

  Also, a list of interference check patterns is obtained, and the list of interference check patterns corresponding to matching information with high priority (no driving record) among the interference check patterns not applied to the interference check target assembly is ranked higher. Rearrange the interference check patterns inside.

  Then, the process proceeds to step S1204, and a screen such as an interference check pattern display screen 1600 shown in FIG. 16 is displayed.

  1601 displays a list of interference check match information rearranged according to the presence or absence of driving results.

  In 1602, the interference check pattern corresponding to the matching information with higher priority in the list of matching information for interference checking is displayed with priority over other interference checking patterns (priority display).

  That is, a master assembly including drive information that has not been applied to the interference check target assembly is displayed with priority over a master assembly including drive information that has been applied to the interference check target assembly.

  As described above, according to the third embodiment of the present invention, it is possible to easily specify the driving method of the parts related to the restriction information of the design object by changing the display priority based on the driving performance. A mechanism can be provided.

<Other embodiments>
A plurality of interference check patterns (master assemblies) may be collectively applied to one interference check target assembly.

  For example, as shown in FIG. 17, when there are three applicable interference check patterns, the first interference check pattern is selected as 1720, and the second interference check pattern is selected as 1730. By pressing the “execute” button, the entity can be driven by the two selected interference check patterns.

  Further, by displaying the identification frame 1731 in a different color for each interference check pattern, the matching information to which the drive information included in each interference check pattern can be identified and displayed, and can be confirmed by the user. For example, the frame color of 1731 and 1733 is red, and the frame color of 1732 and 1734 is blue.

  Further, when an interference check pattern is selected, the interference check pattern specifying tool specifies another interference check pattern in which the interference check pattern and the interference check pattern specifying condition partially or entirely overlap, and displays the interference check pattern.

  For example, as indicated by 1710 and 1720, an interference check pattern (eg, “main rotation” having the same interference check pattern specifying condition as the interference check pattern being selected (eg, “main rotation check” or “main rotation check 2”). "Check" or "Main rotation check 2") is grayed out and displayed in an unselectable state.

  By the identification display, it becomes possible to specify the driving method of the parts related to the restriction information of the design object without duplication.

  That is, the user is notified or / and limited in selection so that different drive information is not applied to the same location at the same time. Therefore, it is possible to prevent the driving direction and accuracy from competing with each driving information, and to perform correct driving according to each driving information.

  Further, in the above-described embodiment, in step S414, it is instructed to operate the component for which each match is set according to the drive information and execute the interference check. For example, the CAD software interference check function ( The function of storing the interference history between the part having the entity and the other part by driving the entity), the parameter of the driving information and the entity to be driven are CAD software so that the interference check of the target part can be easily performed. The interference check pattern specifying tool may be operated so as to notify the user.

  Specifically, at the timing of step S414, the interference check pattern specifying tool instructs to activate the interference check function of the CAD software, and passes drive information to the interference check function of the CAD software.

  The CAD software activates the interference check function in response to the instruction and displays the screen 1800 (FIG. 18). The drive received from the interference check pattern specifying tool in the “target component” and the interference check target assembly in “drive information”. Set the information.

  Then, a user operation for designating an interval for displaying the interference check result in “result display interval” is received, and an entity (having an entity corresponding to the drive information set in “drive information” in response to pressing of the “execute” button) Drive) and record the result of interference check.

  The CAD software displays a list of check results in “interference check results”. In addition, when the “result recording” button is pressed, a list of interference check results displayed in “interference check results” is stored in the external memory 211 in association with the identification information of “target part”.

  That is, by outputting drive information to CAD software, control is performed so that the CAD software can drive components according to the drive information.

  When the interference check pattern specifying tool detects that the process of storing the list of interference check results has been completed normally, the interference check pattern specifying tool generates and stores the drive result 1320 described above.

  The drive information has been described as being stored in the master assembly. However, the drive information is stored in the external memory of the server 200 or the PC 100 as a file different from the master assembly and associated with the match names of the parts in the master assembly. You may make it do. In this case, a combination of the master assembly file and the drive information file is used as one interference check pattern.

  In the above-described embodiment, the match name of the interference check match information is displayed in 712. For example, each match information is applied, and the name of the component whose movement is restricted by the match (part of the component) (Entity name) may be displayed instead of the match name or together with the match name.

  It should be noted that the present invention can be implemented as, for example, a system, apparatus, method, program, or storage medium, and can be applied to a system composed of a plurality of devices. You may apply to the apparatus which consists of one apparatus.
