You can reduce the Motion Analysis simulation time by selecting components and grouping them into a rigid group.
Rigid groups of components behave like a single component in motion calculations:
- Motion between components in the group is ignored.
- Mates between components in the group are ignored.
- All group components contribute to the mass and moment of inertia of the rigid group.
To add a component or subassembly to a rigid group, right-click the component or subassembly in the MotionManager tree, and click Add to New Rigid Group.
If a rigid group contains one fixed component, the rigid group is considered fixed for motion calculations.
