The present invention relates to a design parameter management method, a design parameter management system, and a program document.

More specifically, the present invention relates to a design parameter management method, a design parameter management system, a program, and a storage medium suitable for managing design parameters used in a plurality of different CAD systems. The present invention relates to a computer-readable recording medium.

In this specification, “2D” is appropriately described as “2D”, and “3D” is appropriately expressed as “3DJ”.

BACKGROUND ART In general, for example, in a three-dimensional product design (3D product design) performed in a product development process of an electronic set manufacturer, an electrical packaging design performed using a two-dimensional CAD system (2DC AD system). A collaborative design method is used in which the design and the exterior design process performed using a 3D CAD system (3D CAD system) are linked to each other. T JP2004 / 005306

By the way, in such a conventional cooperative design method, the design parameters and electrical parameters used in a 3D CAD system used in the mechanism exterior design process (hereinafter referred to as “3D mechanical CAD system” as appropriate) are used. The design parameters used in the two-dimensional CAD system used in the mounting design process (hereinafter referred to as “two-dimensional electrical CAD system” as appropriate) are three-dimensional mechanical data (3D mechanical data) and two-dimensional electrical data ( 2D electrical data) and stored in a single file in an integrated and unified state, and managed with their own unique identification numbers (IDs).

Therefore, the mechanical designer who uses the 3D mechanical CAD system and the electrical designer who uses the 2D electrical CAD system log in to the same numbering system and log in the required ID. They were registered as they were acquired, and thereafter the design process was operated in a state where they were managed on this integrated and unified management system. Here, in the conventional management form described above, the configuration itself of the design parameter management system in the three-dimensional mechanical CAD system and the two-dimensional electric CAD system is certainly unified. Therefore, compared to the case where the 3D mechanical CAD system and the 2D electrical CAD system have independent management systems, the system configuration cost can be reduced and the maintenance process can be simplified. There was an advantage that can be. PT / JP2004 / 005306

3 However, the conventional management method described above integrates all the design parameters of the three-dimensional mechanical CAD system and the two-dimensional electrical CAD system. It was pointed out that there was too little flexibility as a system to support all the processes performed for the purpose.

In other words, in the conventional management mode described above, for example, it is possible to integrate design parameters that are more appropriate to proceed independently in a three-dimensional mechanical CAD system and a two-dimensional electric CAD system. As a result, numbering was performed solely for the purpose of creating a file, and a copy of the file created during the numbering was stored separately under a local machine directory. It became common practice to replace existing files under the local machine directory with the files created in the above numbering operation and place them in the integrated management system after the design was completed.

Furthermore, in the conventional management form described above, the concept of shared / non-shared between the three-dimensional mechanical CAD system and the two-dimensional electrical CAD system is not provided, so that the three-dimensional mechanical CAD system and the two-dimensional CAD system are not shared. Design products that do not have a shared relationship with the three-dimensional electrical CAD system and can be quickly completed independently of each other (hereinafter referred to as “non-shared design products” as appropriate) are also referred to as three-dimensional mechanisms. System CAD system and the two-dimensional electrical CAD system depend on the completion of the design of a design product that has a shared relationship (hereinafter referred to as “shared design product” as appropriate). There is a problem in that the design completion time of the entire design is prolonged. P2004 / 005306

Hereinafter, an example of an embodiment of a design parameter management method, a design parameter management system, a program, and a computer-readable recording medium according to the present invention will be described in detail with reference to the drawings of ^ (dimension).

In the embodiment described below, it is assumed that a plurality of different CAD systems and systems are two-dimensional electrical CAD systems, and a three-dimensional CAD system is a three-dimensional mechanical CAD system. 4005306

FIG. 1 shows a configuration diagram of a design parameter management system according to an embodiment of the present invention.

The design parameter management system 10 includes a database unit 12, a data management unit 14, an external storage medium 16, a GUI (Graphical User Interface) display unit 18, an input unit 20, Is configured.

The above-described design parameter management system 10 including the database unit 12, the data management unit 14, the external storage medium 16, the GUI display unit 18, and the input unit 20 can be realized by, for example, a computer system. Here, the database unit 12 can be configured by a general database such as an RDB (relational database).

In the database unit 12, the shared state of each attribute information (the “attribute information” will be described later) in each design parameter is separately registered and managed. That is, the database unit 12 registers various attribute information inherited from the data management unit 14 in a database, and registers the registered attribute information as a virtual shared state in an object that is data modeled (hereinafter, referred to as “shared address”). Object (Sha red Object) ”.) Performs the process to associate with the common parameter.

In addition, this virtual sharing state is not limited to data modeling based on object thinking, but also the relation between database tables in an RDB system. It is also feasible to ship. Next, the data management unit 14 includes a three-dimensional CAD interface unit (3D CAD IZF unit) 14a, a two-dimensional CAD interface unit (2D CAD IZF unit) 14b, It has a geometric information and attribute information separation processing unit (hereinafter simply referred to as a “division processing unit” as appropriate) 14 c and a two-dimensional to three-dimensional geometric conversion converter (2D—3D geometric conversion converter) 14 d. (The “geometric information” will be described later.) The 3D CAD interface unit 14a and the 2D CAD interface unit 14b include an input / output unit (I / o) for an entity file of an OS (Operating System).

Although not particularly shown, the data management unit 14 includes an interface unit with the GUI display unit 18 and the input unit 20, a management unit (application unit) for each process, and the like.

The data management unit 14 specifically means a program aggregate for realizing each of the above-described configurations. Here, the 3D CAD interface unit 14a accesses the 3D mechanism data (the “3D mechanism data” will be described later) and reads internal information to perform editing work such as Z writing. It is an interface.

In addition, the 2D CAD interface unit 14b stores 2D electrical data ("2 The “D electrical data” will be described later. ) Is an interface to access and perform editing work such as reading and writing of internal information.

Next, the power of explaining the segmentation processing unit 14c Usually, the format of the CAD data in the two-dimensional CAD system and the three-dimensional CAD system is geometric information for indicating the physical shape and some form of It is a common format to have attribute information that gives meaning. The segmentation processing unit 14 c is a target of attribute information in order to mutually convert geometric information between 2D and 3D, that is, from 2D to 3D or from 3D to 2D. In a state where the relationship between the geometric information and the attribute information is separately stored, a process of separating the geometric information and the attribute information is performed. The division processing in the division processing unit 14c enables data interchange between a two-dimensional CAD system and a three-dimensional CAD system having different geometric dimensions in the Euclidean space.

The attribute information includes logical data such as electrical property values and material property values assigned to the actual file position (path information), constituent points, surfaces, solid data, etc., in addition to the above-mentioned relevance. Become.

Next, the 2D—3D geometric conversion converter 14d converts the 3D and 2D geometric information into intermediate data after the CAD data in the 3D CAD system is cut into only geometric information, especially in a 2D CAD system. It is converted to conversion intermediate information by the information creation process. This requires data conversion between different CAD kernels in a format that can be understood by each of the Geometry try engines (Geometry try Engine)! ^Because there is ^one life. Then, the 2D-3D geometric conversion converter 14 d converts the intermediate information for conversion into two-dimensional geometric information or three-dimensional geometric information. That is, in the 2D-3D geometric conversion converter 14d, the two-dimensional geometric information is changed and converted into three-dimensional geometric information, and the three-dimensional geometric information is converted into two-dimensional geometric information. Next, the external storage medium 16 can be constituted by a normal storage device such as an HDD (Hard Disk Drive).

Such an external storage medium 16 contains 3D mechanism data 16a, which is an entity file created by a 3D mechanism CAD system, which is a 3D CAD system, and a 2D CAD system. 2D electrical data 16b, which is an entity file created by a 2D electrical CAD system, and geometric information intermediate, which is an entity file created by a 2D-3D geometric converter 14d A file (intermediate geometric information F i 1 e) 16 c is stored. Next, the GUI display section 18 can be constituted by a normal display device such as a CRT, and a user interface is displayed. Next, the input unit 20 can be composed of, for example, a keyboard and a mouse. The user of the design parameter management system 10 inputs necessary instructions to the design parameter management system 10 via the input unit 20. I do. The operation of the above-described design parameter management system 10 in the above configuration will be described.

In the design parameter management system 10, first, the following parameters are set.

That is, using the input unit 20, a shared parameter, that is, an item to be a shared object data modeled as a virtual shared state is determined from the design parameters, and the database unit of the design parameter management system 10 is determined. Set as a shared parameter for 12. This shared parameter is defined as logical on the system.

Here, among the design parameters, items to be used as shared parameters include, for example, a component origin, a component number, a component position, a material, a board outer shape, and a restricted area.

In order for the design parameter management system 10 to recognize each shared parameter from the CAD data in the 3D mechanical CAD system and the 2D electrical CAD system, an attribute association table (matching table: Matching Tab 1 e) is stored in the database. Registered in the section 12 and associates the attribute information registered in the database section 12 with the shared parameter.

FIG. 2 shows an example of an attribute association table in which the genus individual information registered in the database unit 12 is associated with the shared parameter. In the attribute association tape table shown in FIG. Is attribute information that is directly input to each CAD data, and depends on the operation of each CAD system. Line 文字 A character string that is attributed to the geometry of the solid (Solid).

Note that FIG. 6 shows an attribute association table as shown in FIG. 2 in a tree structure, and also shows an explanatory diagram showing a conversion relationship between the 3D mechanism data 16a and the 2D electrical data 16b. I have. An operation example when operating the design parameter management system 10 after performing the above settings will be described below. (1) First step

First of all, the system is logged in from the 3D mechanical CAD system through the 3D CAD interface unit 14a. This design parameter management system 10 accesses the active (Active) CAD data that is file open (File O en) and reads the “mechanism CAD Instance name” set in the attribute association table. Retrieve from the 3D CAD data の of the 3D mechanical CAD system being accessed, and if present, recognize the geometric information of the shared parameters associated with the “mechanical CAD Instance name”. Thereafter, the geometric information is managed as a target of the collaborative design mode, and is placed under the control of the design parameter management system 10.

Geometric information other than shared parameters is treated as non-shared parameter geometric information, and is distinguished from geometric information set in the collaborative design mode. Editing work will be performed independently in the system. (2) Second step

Next, as shown in FIG. 3, while logging in to the design parameter management system 10, the cooperative design setting dialog box is displayed on the GUI display section 18, and the two-dimensional object to be bound (bundled) is displayed. Set 2D CAD data of electrical CAD system. In this case, as in the case of the three-dimensional mechanical CAD system described in the first step, the design parameter management system 10 also transmits the two-dimensional electrical system through the two-dimensional CAD interface unit 14b. Access the inside of the two-dimensional CAD data of the CAD system and acquire the geometric information of the shared parameters associated with the "electric CAD instance name" while referring to the attribute association table. By this process, 3D mechanism data and 2D electrical data are constrained to force S through shared parameters (shared objects). (3) Third step

In the second step, the 3D mechanism CAD data and the 2D electric CAD data are constrained, and the geometric information shared in the constrained mutual data is converted into a 2D—3D geometric transformation in the design parameter management system 10. By using the converter 14d, as shown in Fig. 4, the shape information such as the footprint shape in the two-dimensional electrical CAD system is converted to three-dimensional data, and the three-dimensional mechanical CAD system is used. Shown in Fig. 5 and used for design studies. P2004 / 005306
