Rigid Groups
Use the Rigid Groups tool to define which parts are considered to be grouped together and treated as one rigid body.
Click the satellite icon that appears when you hover over the Rigid Groups tool to view a list of all rigid groups in your model.
Define Rigid Groups
Select which parts to include in the rigid group, then click the Create New Group button.
- You can view which parts belong to a rigid group using the Ground Parts table.
- To ungroup a rigid group, select the group using the arrow keys on the guide bar and click the Ungroup button.
- If a rigid group contains one ground part, the entire rigid group is considered ground.
- Joints, springs, or other connections between parts within a rigid group are ignored for motion analysis.
- You can also define a rigid group by right-clicking on an assembly or part from the Model Browser and choosing Create Rigid Group from the context menu. For assemblies, this method will create a rigid group with the same name as the assembly.
- When you copy and paste a part that belongs to a rigid group, make sure to review your rigid groups. Copy and paste operations may alter your rigid group definitions.
