For an innovative and efficient product development process the use of modern parametric 3D-CAD systems is of increa-sing importance. Basically in the internal digital data structure of a 3D-CAD model geometrical and topological data as well as the modelling history is being stored. Additionally, the feature technology enables the models to be developed with the help of defined zones of geometry with embedded se-mantics. By means of the integration of geometrical and non-geometrical information into the 3D-CAD models it is possible to embed product specific knowledge and design know-how into the models. The department of Computer Integrated Design (DIK) is investigating methods and tools for developing, managing and reusing knowledge-based 3D-CAD-models.
