摘要： Methods for product data management and corresponding systems and computer-readable mediums. A method includes receiving (405) a three-dimensional CAD model in the data processing system, the CAD model including a plurality of geometries. The method includes identifying (410) equivalence relationships between multiple ones of the geometries and receiving at least one Relationship Implication definition. Each Relationship Implication 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 (420) each Relationship Implication definition to the geometries to produce groups of geometries corresponding to each Relationship Implication definition and selecting a representative geometry for each group. The method includes filtering out (435) geometric relationships for each geometry in each group other than the representative geometry and manipulating the CAD model without the filtered-out geometric relationships.

摘要： A method of editing a model comprises receiving (80) an indication of a region of interest in a representation comprising one or more entities, comprising faces of a 3D model, or edges of a 2D model. An edit is determined and all entities in the selected region of interest are tested (81) for the presence of blend entities. All non-blend entities are allocated (82) to an edit group and all blend entities (83) to a test group. All blend entities in the test group are tested (84) to determine whether they comprise boundary blend entities. The edit is applied (87) to all entities in the edit group; and to blend entities which are not boundary blend entities (86). Boundary blend entities are re-blended (88) onto edited entities based on the new position of the entity the boundary blend entity is dependent upon. A representation of the edited region of interest may be output (89).

摘要： A method of editing a model, performed on a data processing system (101), comprises receiving (51) an indication of a change of orientation to be applied to an entity in the model and testing (52) the entity for rotation points to satisfy the change of orientation. If one or more rotation points are present, a rotation point is selected (53, 60) and assessed (54, 61) for conflicts with one or more existing constraints in the system. If no conflict is found, the change in orientation is caused to be carried out (56) by rotation about the selected rotation point. A representation of the edited model is then output (57).
