A Host System for Form Tolerance Specification in the Next-generation GPS based on AutoCAD

Geometrical specification is the bridge to link function, design, manufacture and verification together for a product. The next-generation GPS utilizes duality principle to combine specification and verification of a geometrical product tightly, and to ensure its desired intention (functional requirements). This makes the geometrical specification of a product complete and unambiguous, to reduce uncertainties at different phases in a product life cycle. The geometrical specification system prevailing currently is designed on the basis of traditional rules so that it can’t meet the requirements of the next-generation GPS. This paper presents a host system for form tolerance specification in framework of the next-generation GPS, which is built based on AutoCAD2007.
