Abstract

PURPOSE:To retrieve easily relating part drawings and influence caused by changing a design by providing a data structure using a tree structure matched to the constitution of a product or that of a drawing group with the use of an electric computer. CONSTITUTION:The computer aided drawing control system provides the data structure using the tree structure matched to the constitution of the product or that of the drawing group. The data base having the tree structure is com posed of a projected drawing 10, an entire design drawing 11a relating to the drawing 10, a planned drawing 11b, entire profile drawings 11c and 11d, sub-as sembly design drawings 12a and 12b relating to the design drawing 11a, a part drawing A12c, a sub-assembly drawing 12d and part drawings B, C13a, and C13b relating to the drawing 11d. The data structure is composed of a drawing number control table 23 and a tree structure control table 24. When the table 24 takes out the drawing number, any one of drawing numbers A-F on the corresponding table 23 is specified. Thus the influence scope caused by relating part drawings and changing the design can be easily retrieved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a drawing management system, and more particularly to a drawing management system having a database structure in a two-dimensional design support system using an electronic computer.

[Conventional technology]

Conventionally, this type of drawing management system has been one-dimensional management based on drawing numbers.

[Problem that the invention seeks to solve]

This conventional drawing management method has the disadvantage that when searching for related parts drawings during or after design, or determining the range of influence of a changed part, it is not possible to do so easily using conventional one-dimensional management using drawing numbers. .

[Means for solving problems]

The drawing management method of the present invention is a drawing management method using an electronic computer, and has a data structure based on a tree structure in accordance with the configuration of a product or the welfare of a group of drawings.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows the database structure of a group of drawings in which drawings are managed in a tree structure according to an embodiment of the present invention. In FIG. 1, the present embodiment is a drawing management system using an electronic computer, and includes a tree-structured database that matches the structure of a product or a group of drawings. The management means for this tree-structured data base is, for example, a planning drawing, an overall design drawing 11a, a planning drawing 11b, an overall appearance drawing 11, etc.
C1 and overall design drawing 1], d, and overall design drawing 1
] Sub-As5y design drawing 12a and sub-As5y design drawing 12b related to a, overall drawing 1] Parts drawing 12c and sub-As5y assembly drawing 12c related to C, and further parts drawing related to this sub-As5y assembly drawing 12 13a and a parts drawing 13b.

FIG. 2 shows a data structure that realizes the tree structure of this embodiment. In FIG. 2, this embodiment introduces a data structure having a figure number management table 23 and a tree structure management table 24. The figure number management table 23 performs management using conventional figure numbers, and the tree structure management table 24 Manage the tree structure between drawing numbers.

That is, in this embodiment, when a drawing number is extracted from the tree structure management table 24, the corresponding drawing number management table 2
One of the drawing numbers A to F of No. 3 is specified, and one of the drawing numbers A to F is taken out.

〔Effect of the invention〕

As explained above, the present invention manages drawing numbers using a tree structure, so that it can be used to display drawings that require relationships between drawings, for example, to see the range of influence of a design change, or to refer to related drawings of certain parts. It has the effect of making it easy to collect.

[Brief explanation of drawings]

Claims (1)

[Claims] A drawing management method using an electronic computer, which is characterized by providing a data structure using a tree structure that matches the structure of a product or a group of drawings.
