Global Consistency Management within a CAD Framework

Consistency Guarantees the correctness of information. Within a CAD Framework, there are several components which deal with different aspects of consistency management depending on the different tasks of the components. Presently, every component has its own language for the definition of constraints, its own functionality and its own mechanism for the evaluation of constraints. This paper presents the idea of a global consistency management system within a CAD Framework. It presents the different aspects of consistency related to the different components of a CAD Framework and offers strategies for defining and administering constraints in a uniform way. (IGD
