Feature-based parametric assembly modelling (FbPAM) is an approach to assembly modelling in CAD/CAM that integrates the advantages of features-based modelling and parametric modelling. The realization of FbPAM systems requires an appropriate representation scheme. Here, a parametric assembly feature representation (PAFRep) is introduced that incorporates the application data of a feature-based model with the generic data of a parametric model. The PAFRep represents explicitly assemblies and assembly relationsships between parts as well as design or manufactoring features and their relationships. Application specific data is mapped to generic form entities and to geometric and non-geometric parameters and constraints.
