Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a component configuration management method for a computer-aided design and drawing system, and particularly to a component configuration management method suitable for designing components constituting a tree structure.

[Conventional technology]

In recent years, computer-based design and drawing systems (so-called CAD systems) have become widely used. Conventional devices of this kind, as described in Japanese Patent Application Laid-Open No. 59-220867, create a parts list from drawings created using a computer-aided design system, or provide parts information from the parts list to drawings. Generally, data consistency between systems is maintained.

[Problem that the invention seeks to solve]

One product is made up of many parts, and most of the parts generally have a tree structure. However, in conventional CAD systems, each created drawing is independent, and relationships such as parent-child relationships between drawings are not considered.
When performing consistent design work from planning to detailed design using a CAD system, there has been a problem in that independent drawings cannot be managed hierarchically.

An object of the present invention is to provide a CAD system that supports the design of parts constituting a tree structure.

[Means for solving problems]

The above purpose is to create a parts management table for managing the hierarchical structure of parts and a parts composition layer management table for managing the usage status of the layers that make up the part shape for each part. This is achieved by associating management tables.

[For production]

Assemble parts in the parts management table corresponding to each part.

By storing a pointer to the parts management table of child parts and parallel parts and following this pointer.

Know the parent parts, child parts, and parallel parts of a certain part. Therefore, even if the hierarchy of one part configuration becomes deep, all upper and lower parts can be known by sequentially following the pointer.

In addition, the 1-part management table has a pointer to the figure management table that manages the figures that make up the part shape, and when the 1-part shape is composed of multiple figures, the 1-piece management table is chained with the pointer, so one part You can easily know the figures that make up a shape.

Furthermore, the 1 part management table has a pointer to the part composition layer management table that manages the usage status of the layers that make up the 5 part shape.The 0 part t+W stratification management table has as many points as the number of layers in use, and has a pointer. It is chained with.

In this table, which layer of the child parts should be assembled based on the layer numbers of the six parts themselves and the layer numbers of the assembled parts, which store information such as the placement position of the parts and rotation angle 1 reversal information of the assembled parts. It is possible to know in which layer of the part the parts are placed. From the placement position in the assembled part and the rotation angle of the assembled part, you can see where the child part is placed in the assembled part and how much it is rotated.1 From the reversal information, you can reverse the defined part shape. You can know whether it is being used or not.
