Integration of design object models is one of the expected roles of intelligent CAD systems. This paper deals with maintenance of relationships among models. We examine the nature of models and show that knowledge about relationships among background theories is crucial for the integration. Based on this discussion, we propose the metamodel mechanism, a new framework for integrated design object modeling. The idea of the metamodel mechanism is to utilize a qualitative model in order to represent dependency among concepts of which the models consist. The metamodel is refined through the design process by four operations, viz. instantiation, unification, specialization, and delegation. We also show an implementation of the metamodel mechanism.
