Knowledge-based and agent-supported modeling in the field of parametric 3D-CAD systems

Current research activities aim to enhancing parametric and feature-based 3D-CAD systems towards representing, processing and distributing knowledge. This paper describes the fundamental ideas concerning knowledge integration in the field of parametric 3D-CAD systems. A discussion of state-of-the-art 3D product modeling is presented followed by an insight into the research on 3D-CAD components considering knowledge-based engineering (KBE). A summary of current implementations of knowledgeware in the leading 3D-CAD systems is included. Further research and development activities of the Department of Computer Integrated Design (DIK) on knowledge-based modeling methods are addressed. In addition, a current research project is presented which includes the development of adaptive and knowledge-based 3D-CAD design components. The management of the knowledge-based methods developed in the research project has to be implemented by means of agent technology. The paper concludes with a view of integrated knowledge processes and knowledge representations in the field of 3D-CAD components.
