Abstract

PURPOSE:To efficiently perform similar design by generating a component drawing only by correcting and changing an assembling drawing by linking the shape of each constituent component of the assembling drawing with that of the component drawing corresponding to the above. CONSTITUTION:A targeted data base is called, and an input mode is set at a mode for working. Next, a display mode is set in such a way that the shape data display for working and for all of the components are set as YES, and the display modes of all of the data other than that as NO, and the data are displayed on an output device 1. Next, the change, the correction, and the addition of a graphic being displayed in an interactive format are performed by a worker, and added graphic element is allocated on each component shape data part. Only the shape data and auxiliary data corresponding to the shape data of each component is taken out, and the file of the component drawing is generated. After generating the files of all of the component drawings, each component drawing is displayed on the output device 1, and insufficient size or shape, etc., are added in the interactive format, then, the component drawing is accomplished.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a drafting support system that automatically creates parts drawings by simply creating assembly drawings in an interactive manner based on a database.

[Summary of the invention]

The present invention enables a CAD system that performs drawing with the aid of a computer to display and erase the drawings of the parts that make up the assembly drawing as independent data, and when the drawings of all the parts are displayed, By structuring the data so that it can be recognized as a diagram, simply changing or correcting the assembly drawing automatically changes the parts drawing.

[Conventional technology]

Conventionally, when performing design work, a method has been used in which an assembly drawing is first created, and then parts diagrams of the component parts are created based on the assembly drawing.

[Problem to be solved by the invention]

However, with this method (11) it takes a lot of effort and time to create part drawings, and the design efficiency is poor.

(2) Drawing errors persist when creating parts drawings from assembly drawings.

There were issues such as:

In order to solve these conventional problems, the present invention links the shape of each component in an assembly drawing to the corresponding shape of the parts drawing, thereby creating a parts drawing simply by modifying or changing the assembly drawing. The purpose of this project is to establish a drafting support system that can efficiently create similar designs.

[Means to solve the problem]

In order to solve the above problems, in the present invention, as shown in FIG. It is now possible to create parts drawings simply by changing and correcting assembly drawings in an interactive format.

[Effect]

By constructing a database with the above-mentioned data structure and devising work procedures, it is possible to save time and effort in creating parts diagrams, and to efficiently perform similar designs and design changes.

〔Example〕

Embodiments of the present invention will be described below based on the drawings. Second
The figure is a configuration diagram of a CAD system when the present invention is implemented. Output device 1 for displaying drawing data to workers
, an input device 2 for inputting data, and a database 4 structured so that each part can be stored independently, and a data processing unit 3 manages these, corrects and adds data, creates data for output, etc. As shown in Figure 1, the database 4 includes a work part that stores data entered by the operator, a shape part that stores shape data for each part, and a shape corresponding to each part. data other than (dimension lines,
It consists of an auxiliary part that stores drawing frames, etc.), and the following two modes can be set for each data part.

1) Input mode Specifies the data section that stores the data input from the input device. Only one location can be specified.

11) Display mode Specify whether to display each data section on the output device. YES for all data sections (display)
, No (do not display).

Furthermore, when all the shape data of each part is displayed on the output device, it is arranged in a layout that allows the operator to recognize it as an assembly drawing.

FIG. 3 is a flowchart showing an embodiment of the present invention, showing the procedure for creating assembly drawings and parts drawings.

First, in step A, the target database is called up and the input mode is set to "work".

Thereafter, data input by the worker is once stored in this work data section.

Next, set the display mode of "for work" and the shape data of all parts to YES, and set the display mode of all other data to N.
Set to O and display the data on the output device.

(Steps B and C) As a result, the shape data is displayed on the output device as if it were an assembly drawing.

Next, using well-known drawing creation/editing software for CAD, the operator is made to change, modify, and add to the displayed figures in an interactive manner. (Step D) The data added at this time is stored in the work data section according to the settings in step A.

After the work is completed, the work data section is searched and the input graphic data is assigned to the corresponding part shape data section. (Step E) For each part, only its shape data and corresponding auxiliary data are extracted to create a parts diagram file. (Step F.

G) After creating a file of all parts diagrams, display each part diagram on the output device and add missing dimensions, shapes, etc. in an interactive manner to complete the parts diagram. (Step H) FIG. 4 is an example of data displayed on the output device.

〔Effect of the invention〕

As explained above, the present invention constructs a database with an independent structure for each part and devise work procedures to simultaneously modify assembly drawings and parts drawings.

It has become possible to make design changes and similar designs efficiently.
