Technique for Checking Design Rules for Three-Dimensional CAD Data

摘要

A technique was developed for checking whether threedimensional CAD shape satisfies design rules. Many design rules related to reliability and manufacrurability should be considered in the design stage. Our technique automatically recognizes feature shapes such as a rib and boss from a CAD model shape, and it checks the shape and arrangement. The effectiveness of the technique was demonstrated in a test of the injection-molded part
