CAD system and methods

Abstract

A computer-aided-design system used with a computer forms a shape model for applications of a product to be manufactured. A plurality of shape forming function information having forming commands for various shapes of the product for expressing in the shape model for the applications is included to form the shape model for the applications based on a selection of the shape forming function information. The shape model for the applications can be defined by its shape derived from a basic shape. Further, the shape forming function information of the shape model for the applications can be defined as a set of the forming commands that correspond to the basic shape and the forming command corresponding to a shape derived from the basic shape. Thus by effectively controlling the shape of each desired model, a simple model forming process can be performed.
