Abstract
Methods for product data management and corresponding systems and computer-readable mediums. A method includes receiving a three-dimensional CAD model in the data processing system, the CAD model including a plurality of geometries. The method includes identifying equivalence relationships between multiple ones of the geometries and receiving at least one Relationship Implication (RI) definition. Each RI definition defines a relationship implication according to a plurality of the geometries and at least one type of the equivalence relationships. The method includes applying each RI definition to the geometries to produce groups of geometries corresponding to each RI definition and selecting a representative geometry for each group. The method includes filtering out geometric relationships for each geometry in each group other than the representative geometry and manipulating the CAD model without the filtered-out geometric relationships.
