Abstract

Tolerance representation in a CAD data structure demands a user interactive environment which enables the user to input the tolerance information in both the unevaluated (CSG) and in the evaluated (B-Rep) databases (4]. This requires an effective linking mechanism between the CSG and the B-Rep data models at each stage of the object development. This has been achieved through the development of a reference face list. Tolerance information has been attached with this face list as "constraint nodes," which are formed and updated after each "set operation." Several functions have also been developed to retrieve essential information from the data structure in order to answer various queries.
