Feaure-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 relationships between parts as well as design or manufacturing features and their relationships. Application-specific data is mapped to generic form entities and to geometric and non-geometric parameters and constraints.
