[0001]
The present invention relates to a design parameter management method, a design parameter management system, a program, and a computer-readable recording medium, and more particularly, a design suitable for use in managing design parameters respectively used in a plurality of different CAD systems. The present invention relates to a parameter management method, a design parameter management system, a program, and a computer-readable recording medium.
[0002]
In the present specification, “2D” is appropriately expressed as “2D”, and “3D” is appropriately expressed as “3D”.
[Background]
[0003]
In general, for example, in a 3D product design (3D product design) performed in a product development process of an electronic set manufacturer, an electrical packaging design process and a 3D CAD system performed using a 2D CAD system (2D CAD system) A collaborative design technique is adopted in which the design is advanced while associating with each other a mechanism exterior design process performed using the (3D CAD system).
[0004]
By the way, in such a conventional collaborative design method, design parameters used in a three-dimensional CAD system used in the mechanism exterior design process (hereinafter appropriately referred to as “three-dimensional mechanism CAD system”) and the electrical packaging design process are used. Design parameters used in a two-dimensional CAD system to be used (hereinafter referred to as “two-dimensional electric CAD system” as appropriate) include three-dimensional mechanism data (3D mechanism data) and two-dimensional electric data (2D electric data). It was stored in one file in a unified state, and managed with a unique identification number (ID).
[0005]
Therefore, the mechanical designer who uses the three-dimensional mechanical CAD system and the electrical designer who uses the two-dimensional electrical CAD system log in to the same numbering system and acquire the necessary IDs. After that, the design process was operated in a state of being managed on the integrated centralized management system.
[0006]
Here, in the conventional management mode described above, the configuration itself of the design parameter management system in the three-dimensional mechanical CAD system and the two-dimensional electrical CAD system is certainly unified. Therefore, compared with the case where the three-dimensional mechanical CAD system and the two-dimensional 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 of being able to.
[0007]
However, the above-described conventional management form integrates all the design parameters of the three-dimensional mechanical CAD system and the two-dimensional electrical CAD system, so that, in the first place, for the different design purposes of mechanical exterior design and electrical packaging design. It was pointed out that the system that supports all the processes to be performed was too flexible.
[0008]
That is, in the above-described conventional management mode, for example, even design parameters that are more suitable to proceed with the design independently in each of the three-dimensional mechanical CAD system and the two-dimensional electrical CAD system are under integrated management. As a result, the numbering act was performed only for the purpose of creating the file, and after that, a copy of the file created in the numbering act was stored and managed separately under the local machine directory. The operation of replacing the file stored and managed under the local machine directory with the file created in the above numbering action and putting it in the integrated management system has become common.
[0009]
Further, in the above-described conventional management mode, the 3D mechanical CAD system and the 2D electrical system are not shared by the concept of sharing / non-sharing between the 3D mechanical CAD system and the 2D electrical CAD system. Design artifacts (hereinafter referred to as “non-shared design artifacts” as appropriate) that have no shared relationship with the system CAD system and can complete early design independently of each other are also referred to as three-dimensional mechanical CAD systems. It depends on the completion of the design of a design product that is shared with the two-dimensional electrical CAD system (hereinafter referred to as “shared design product” as appropriate), and as a result, the entire product design is completed. There was a problem of prolonging the time.

Hereinafter, an example of embodiments 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 accompanying drawings.
[0035]
In the embodiment described below, a two-dimensional CAD system and a three-dimensional CAD system are used as a plurality of different CAD systems, the two-dimensional CAD system is a two-dimensional electrical CAD system, and the three-dimensional CAD system is It is assumed that it is a three-dimensional mechanical CAD system.
[0036]
FIG. 1 is a block diagram of a design parameter management system according to an example of an embodiment of the present invention.
[0037]
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, and an input unit 20. ing.
[0038]
The 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 a computer system, for example.
[0039]
Here, the database part 12 can be comprised by general databases, such as RDB (relational database), for example.
[0040]
In this database unit 12, the sharing state of each attribute information (“attribute information” will be described later) in each design parameter is separately registered and managed.
[0041]
That is, the database unit 12 registers various attribute information inherited from the data management unit 14 on the database, and data modeled object (hereinafter referred to as “shaded object (hereinafter,“ shaded object ”) with the registered attribute information as a virtual shared state. Shared object) ”).
[0042]
This virtual sharing state is based on object thinking. Z In addition to data modeling, the present invention can also be realized by relationships between database tables in the RDB system.
[0043]
Next, the data management unit 14 includes a three-dimensional CAD interface unit (3D CAD I / F unit) 14a, a two-dimensional CAD interface unit (2D CAD I / F unit) 14b, An information and attribute information segmentation processing unit (hereinafter simply referred to as “segmentation processing unit” as appropriate) 14c and a two-dimensional / three-dimensional geometric transformation converter (2D-3D geometric transformation converter) 14d are configured. (“Geometric information” will be described later). The three-dimensional CAD interface unit 14a and the two-dimensional CAD interface unit 14b include an OS (operating system) actual file input / output unit (I / O) as a part of them.
[0044]
Although not particularly illustrated, 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.
[0045]
The data management unit 14 specifically means a program aggregate for realizing the above-described configurations.
[0046]
Here, the three-dimensional CAD interface unit 14a is an interface for accessing 3D mechanism data (“3D mechanism data” will be described later) and performing editing operations such as reading / writing of internal information. .
[0047]
The two-dimensional CAD interface unit 14b is an interface for accessing 2D electrical data (“2D electrical data” will be described later) and performing editing operations such as reading / writing internal information.
[0048]
Next, the separation processing unit 14c will be described. Usually, as the format of CAD data in the two-dimensional CAD system and the three-dimensional CAD system, geometric information for indicating a physical shape and some meaning for the geometric information are used. It is a general form to have attribute information that gives In order to mutually convert geometric information between 2D and 3D, from 2D to 3D or from 3D to 2D, this segmentation processing unit 14c is a target of attribute information. In a state where the relationship between the information and the attribute information is stored separately, a process for separating the geometric information and the attribute information is performed. Such a separation process in the separation processing unit 14c enables data compatibility between a two-dimensional CAD system and a three-dimensional CAD system having different geometric dimensions in the Euclidean space.
[0049]
In addition to the above-mentioned relevance, the attribute information also includes logical data such as electrical property values and material property values assigned to the position (path information) of the entity file, composition points, surfaces, solid data, etc. Become.
[0050]
Next, after the CAD data in the 2D-CAD system and the 3D-CAD system is divided into only the geometric information, the 2D-3D geometric conversion converter 14d generates intermediate information for converting the 3D- and 2D-geometric information. Is converted into intermediate information for conversion. This is because, in order to perform data compatibility between different CAD kernels, it is necessary to convert the data into a format that can be understood by each Geometry Engine.
[0051]
Then, the 2D-3D geometric conversion converter 14d converts the conversion intermediate information 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.
[0052]
Next, the external storage medium 16 can be configured by a normal storage device such as an HDD (Hard Disk Drive).
[0053]
Such an external storage medium 16 is created by 3D mechanism data 16a, which is a substantial file created by a 3D mechanism CAD system that is a 3D CAD system, and by a 2D electric CAD system that is a 2D CAD system. The 2D electrical data 16b, which is the created entity file, and the geometric information intermediate file (geometric information intermediate file) 16c, which is the actual file created by the 2D-3D geometric conversion converter 14d, are stored.
[0054]
Next, the GUI display unit 18 can be configured by a normal display device such as a CRT, for example, and a user interface is displayed.
[0055]
Next, the input unit 20 can be configured by, for example, a keyboard or a mouse, and the user of the design parameter management system 10 inputs necessary instructions to the design parameter management system 10 via the input unit 20.
[0056]
With the above configuration, the operation of the design parameter management system 10 will be described.
[0057]
In this design parameter management system 10, first, the following parameters are set.
[0058]
That is, the input unit 20 is used to determine a shared parameter, that is, an item to be a shared object that is modeled as a virtual shared state, from among the design parameters, and to the database unit 12 of the design parameter management system 10. To set as a shared parameter. This shared parameter is defined as logical on the system.
[0059]
Here, items to be shared parameters from among the design parameters include, for example, the component origin, the component number, the component position, the material, the board outline, and the restricted area.
[0060]
In addition, in order for the design parameter management system 10 to recognize each shared parameter from CAD data in the 3D mechanical CAD system and the 2D electrical CAD system, an attribute association table (matching table) is registered in the database unit 12. The attribute information registered in the database unit 12 is associated with the shared parameter.
[0061]
FIG. 2 illustrates an example of an attribute association table in which attribute information registered in the database unit 12 is associated with a shared parameter. In the attribute association table illustrated in FIG. 2, “Instance name” refers to each CAD data. Attribute information that is directly input to, and these are character strings that are attributed to a line or solid geometry by the operation of each CAD system.
[0062]
FIG. 6 shows an attribute association table as shown in FIG. 2 in a tree structure and an explanatory diagram showing the conversion relationship between the 3D mechanism data 16a and the 2D electrical data 16b.
[0063]
An example of operation when the design parameter management system 10 is operated after performing the above setting will be described below.
[0064]
(1) First step
First, a system login is performed from the three-dimensional mechanical CAD system through the three-dimensional CAD interface unit 14a. The design parameter management system 10 accesses the active CAD data that has been opened (File Open), and the “mechanism CAD instance name” set in the attribute association table is currently being accessed. A search is made from the three-dimensional CAD data of the system CAD system, and if it exists, the geometric information of the shared parameter associated with the “mechanism CAD instance name” is recognized. Thereafter, the geometric information is managed as a target of the collaborative design mode, and is placed under the management of the design parameter management system 10.
[0065]
Geometric information other than the shared parameters is handled as geometric information of non-shared parameters, and is separately edited in the three-dimensional mechanical CAD system in distinction from the geometric information set in the collaborative design mode.
[0066]
(2) Second step
Next, as shown in FIG. 3, a collaborative design setting dialog is displayed on the GUI display unit 18 while logged in to the design parameter management system 10, and the two-dimensional electric CAD system to be bound (bundle) is displayed. Set two-dimensional CAD data. Also at this time, as in the case of the three-dimensional mechanical CAD system described in the first step, the design parameter management system 10 passes through the two-dimensional CAD interface unit 14b and the two-dimensional CAD of the two-dimensional electric CAD system. By accessing the inside of the data and referring to the attribute association table, the geometric information of the shared parameter associated with the “Electric CAD Instance name” is acquired. By this step, the 3D mechanism data and the 2D electrical data are constrained through the shared parameter (shared object).
[0067]
(3) Third step
The 3D mechanism CAD data and the 2D electric CAD data are constrained by the second step, and the geometric information shared in the constrained mutual data is converted into the 2D-3D geometric conversion converter 14d in the design parameter management system 10. As shown in FIG. 4, as shown in FIG. 4, the shape information such as the footprint (FootPrint) shape in the two-dimensional electrical CAD system is three-dimensionalized and displayed on the three-dimensional mechanical CAD system for use in design studies. Also, as shown in FIG. 5, the material information in the three-dimensional CAD data in the three-dimensional mechanical CAD system is reflected in the substrate data (two-dimensional CAD data) in the two-dimensional electric CAD system and specialized in electrical characteristics. Clearance verification can be performed.
