[Industrial application field]

The present invention relates to a computer-aided installation system, and particularly to an improvement in a method for creating a parts list.

In recent years, computer-aided design systems (CAD systems), which create design drawings on a display screen with the aid of a computer, have become popular.

One way to use this CAD system is to automatically pick out the parts to be used from the design drawings and create a purchasing/production bill of materials for manufacturing, but conventional CAD Since the system could only perform aggregation and tabular output in a certain format, there was the issue of having to provide a parts list creation program compatible with the products to users who manufacture a wide variety of products. Ta.

For this reason, there is a need for a comviator-aided design system that has a standardized parts list creation function.

[Conventional technology]

+1. l Create part graphic data on the display screen based on the design function provided by the CAD system.

(2) Input attribute data such as part name (1) part model number, material (1) weight, etc., and register together with graphic data.

(3) When creating design drawings for the product (Mi product),
Quoting the registered parts and placing them on the display screen.

(4) After the arrangement is completed, a part number (identical parts are given the same part number) is assigned on the display screen.

As a result, the cited part data (graphic data, attribute data) is filed based on the part number, and the number of used parts is counted.

(5) When an instruction is given to create a parts list, the parts list creation unit (not shown) writes the attribute data, quantity, etc. Create a parts list by inputting and output it.

[Problem to be solved by the invention]

The contents of the parts list often differ depending on the product, especially for production/! ',! In the case of a required parts list, items specific to the user or the product are required, such as the place of purchase and the size of the materials.

Second, if the items are different, the type of data (letters, numbers), data length (number of characters), etc. to be entered in this item will be different.

For this reason, conventionally, users have been provided with a product-compatible parts list creation program that sets a parts list format corresponding to the product and enters predetermined data corresponding to the format I□.

For this reason, the system provider has to develop a program compatible with the product, and there is a problem in that it is not easy for the user to change the format of the parts list.

In view of the above problems, it is an object of the present invention to provide a computer-aided design system with a standardized parts list creation function.
