CAD system, design-support program for CAD system, and design methods

摘要

A computer-aided-design (CAD) system design-support program and design methods are provided where a generation command to generate a target shape is extracted from existing CAD data. The generation command is displayed so as to make it possible to arbitrarily select a parameter included in the generation command. An operator is allowed to add a shape command to the selected parameter. Together with the parameter that includes the added shape command, the generation command is stored as a macro program. The macro program is activated and executed by inputting parameters provided with the shape commands, so as to change a target shape into a desired shape. With these arrangements, a CAD system as well as a design-support program and a design method allows more efficient operation of a user.
