Rigid Groups

Use the Rigid Groups tool to group bodies into a rigid group.

To group Rigid Bodies such that they move together as one rigid body:
  1. From the Geometry ribbon, click the Rigid icon.
  2. Use the Bodies collector on the guide bar that appears to select the bodies to be grouped.
    • Use the Ctrl key to add more bodies to the group.
    • Use the Shift key to remove bodies from the group.
  3. Click the button in the modeling window to create the group.
  4. Use the entity selector on the left of the guide bar to select an existing group to edit.
    • Use the Ctrl key to add more bodies to the group.
    • Use Shift key to remove bodies from the group.
    • Click Ungroup to delete the rigid group.
Note:
  • A body cannot belong to more than one group.
  • Deleting a rigid group does not delete the bodies that were part of the rigid group.
  • Any connections between the bodies within a rigid group will not be realized to the solver.
  • A property editor provides information about the aggregated mass, inertia and CG of the rigid group.

  • A rigid group can be grounded using the Ground check box in the property editor.
