Abstract:
The complexity of a CAD model is reduced while its kinematic integrity is maintained by unloading certain data associated with the CAD model from the main memory of a computing device used in the design of the CAD model. The unloaded data includes graphics data and geometry data of those components of the CAD model that the user selects to suppress. The constraint data of the suppressed components are, however, retained in main memory so that the movements of the components of the CAD model can be modeled accurately. By unloading data from the main memory, the overall performance of the computing device is improved and also frees up memory resources for other uses.
