   • Select Rotate if you want to “spin” the object.
   • Select Rotate Around if you want the other objects in the selection group rotate to around the manipulation point.
   • If you want to rotate objects incrementally, use the Snap Angle button. See Snap Rotation.
     Note

     When in Rotate transformation mode, the reference menu includes the Layer (Additive) option.

3. Select the object’s rotation rings in the Viewer window and drag them or enter precise values in Properties windows.
