Abstract:
Systems, program products and program products for accepting a request to move a first geometric entity that is constrained to other geometric entities in a drawing that may contain both one-way and two-way geometric constraints. A set of affected geometric entities that need to be repositioned or otherwise changed as the result of moving the first geometric entity is identified. The affected geometric entities and the geometric constraints are classified into groups which are solved using a variational geometric constraint solver. If the geometric constraints cannot be satisfied, the movement of the first geometric entity is restricted. Otherwise the affected geometric entities are updated.
