Rigid Groups

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.
You can drag components, folders, or subassemblies into and out of rigid groups.
You cannot drag individual components of a rigid sub-assembly into a rigid group.
If a rigid group contains one fixed component, the rigid group is considered fixed for motion calculations.
When you add components containing mates to a rigid groups, the mates are listed in the MotionManager design tree under the rigid group.
