As long as your object has group names matching the saved actor names the rig saved to the library will attach itself to that new obj. Make sure you have the new mesh selected before entering setup room. It just transfers that rig to the new object. You won't encounter this but... when performing figure surgery, deleting bones etc, and exiting the set up room, the polys that were formerly attached to deleted bones will remain in the scene as 'figure set up' prop. If you don't need those left overs they're safe to delete.

Edit_ extrapolate as you will as to how this might be useful as a quick way to delete polys in poser.
