HP PE/SolidDesigner: Dynamic Modeling for Three-Dimensional Computer-Aided Design
In most solid modeling CAD systems, knowledge of the history of the design is necessary to avoid unanticipated side-effects when making changes. With dynamic modeling, local geometry and topology changes can be made independently of the model creation at any time, using both direct and dimension-driven methods. The core components enabling dynamic modifications are the tool body and the relation solver.
