Modeling Entities Missing in Optimized Alternative


When you optimize a design space using motion loads, the resulting shape appears as an alternative in the Model Browser, and sometimes modeling entities do not appear in the optimized alternative. This is a known issue, and to avoid it you should take precautions to ensure that your modeling entities are not directly connected to a design space.


  1. Always apply loads, supports, and other modeling entities to non-design space parts.
  2. Use the Partition tool to create non-design space parts at the region of connection and place both the design space and non-design space parts into a single rigid group.
  3. Re-establish your connections (spring, motor, etc.) to act between the partitions and the rest of the model.
