Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a development support system such as a CAD system used for designing components of various mechanical devices such as those for automobiles.

(Prior Art) Currently, computer-based design support systems (CAD systems) are being developed in various fields.

This C, AD system is currently ahead of the curve in the field of electronic components such as ICs that have repeated wiring patterns with relatively linear shapes, and is suitable for mechanical components with complex shapes. seems to be lagging behind in this field.

A CAD system that designs mechanical parts registers a large amount of shape data for each part that makes up the product to be designed in a database, and then selectively retrieves the necessary shape data from the database to create it. It is designed to be incorporated into the drawing inside.

As typical software for operating such a CAD system, the product names rC and ADAMJ, which are sold by CADAM, are known. This r
CAT) AM and I have a function to hold graphic data in the form of one parent screen and multiple child screens subordinate to this parent screen on the work border, a function to draw on these surfaces and child screens, and a function to draw on these screens and child screens. A function to copy data between parent screens, a function to select one of the data files that make up the database and copy the shape data held there to one of the child screens, and a function to save data on the main screen to a save file. It has functions such as output.

As disclosed in Japanese Patent Application No. 63-138466, etc., the shape data registered in the above database can be managed using a tree consisting of parent parts and child parts. There are things that are managed in the form of structures.

(Problems to be Solved by the Invention) In the conventional CAD system for the above-mentioned mechanical parts, shape data stored in a database is managed in a tree structure format. For this reason, it is necessary to create a tree structure for each product to be designed, which poses a problem of requiring labor and time.

Furthermore, each time a component is changed due to a design change, it is necessary to change the tree structure, which is a problem in that it is labor-intensive and time-consuming.

Furthermore, in conventional CAD systems, since the data stored in the database is mainly shape data, they tend to remain as a core drafting support system. For this reason, it is necessary to transfer knowledge about past achievements, know-how, etc. from design experts to design personnel orally or in writing.

In addition, in conventional CAD systems, the data stored in the database is mainly shape data, so when designing a new item that has not been used, it is necessary to search for documents that record past experimental data and conduct experiments. There is a problem that it takes time to design.

Furthermore, in conventional CAD systems, parts are classified using a unique method that takes only the efficient operation of this system into consideration. For this reason, there is also the problem that it becomes difficult for designers who are used to classification methods based on conventional in-house standard parts and the like before the introduction of the CAr) system.

Furthermore, in addition to the shape data of the part, drafting also requires the writing of additional symbols specifying surface roughness, dimensional accuracy, etc. However, conventionally, such additional codes have not been registered in a database, so there is a problem that designing them requires a lot of effort and time.

In addition, conventional CAD systems only deal with design drawings, and specifications that describe how to confirm characteristics and the like are prepared in separate documents. For this reason, the amount of effort and time required to create specifications in a series of design tasks is increasing.

(Means for Solving the Problems) According to the development support system of the present invention, various parts constituting a part to be designed are classified into a plurality of part standards while being grouped based on the connection method of each element, For each part standard, a file of shape data is created as part of the data file.

Further, - for at least a part of the part standard, a design guide file in which design considerations are described and a supporting data file including experimental data are created as part of the data file.

Further, various parts constituting the part to be designed are classified using criteria different from the part standard, and files of shape data of these parts are created as part of the data file.

Drafting standard data including drawing frames and drafting symbols is also created as part of the data file.
