In SpaceClaim, create a solid for the static zone then hide that solid. Create another solid for the rotating zone. Unhide the static zone solid then use the Combine tool to subtract the rotating zone from the static zone. You might end up with three solids. Delete the extra copy of the rotating zone that was created by the Combine tool. Now you will have two zones with no overlap. On the Workbench tab, click on the Share button.  This creates shared topology in the same way that "Form New Part" does in DesignModeler.
