Identification and management of redundancy within geometric relationships

A data processing system comprising:

• a processor;
• and
• an accessible memory, the data processing system particularly configured to
• receive a three-dimensional CAD model in the data processing system, the CAD model including a plurality of geometries;
• identify equivalence relationships between multiple ones of the geometries;
• receive at least one Relationship Implication (RI) definition, each RI definition defining a relationship implication according to a plurality of the geometries and at least one type of the equivalence relationships;
• apply each RI definition to the geometries to produce groups of geometries corresponding to each RI definition;
• select a representative geometry for each group;
• filter out geometric relationships for each geometry in each group other than the representative geometry;
• and
• manipulate the CAD model without the filtered-out geometric relationships.

A non-transitory computer-readable medium encoded with executable instructions that, when executed, cause one or more data processing systems to:

• receive a three-dimensional CAD model in the data processing system, the CAD model including a plurality of geometries;
• identify equivalence relationships between multiple ones of the geometries;
• receive at least one Relationship Implication (RI) definition, each RI definition defining a relationship implication according to a plurality of the geometries and at least one type of the equivalence relationships;
• apply each RI definition to the geometries to produce groups of geometries corresponding to each RI definition;
• select a representative geometry for each group;
• filter out geometric relationships for each geometry in each group other than the representative geometry;
• and
• manipulate the CAD model without the filtered-out geometric relationships.
