In WF3, View > View Manager > All tab. The only thing that really tells you it's a combined state is that the default name is "Comb0001" when you created a new view there. Hope this helps. Tyler
To follow up on Tyler's suggestion, you can modify the new state by clicking edit --> redefine. You'll get this pop up:
Combined states are very useful for setting up an exploded view drawing of simp reps. When you add a new drawing view you'll be prompted for the combined state and your view will already be set up for view, exploded state, and simp rep state.
