Improved Intrepid Class Star ship role playing room 4 Decks (Bridge, Crew deck, Engine Room, and Shuttle bay) + 2 "addon" deck areas (use my addon crew/science, security, or other decks)
Uses my turbolift system, click the deck you want, zoom your camera all the way in, spin the camera around to find another dot to click on the deck you are on.
This model uses some shapes found in a Goggle Warehouse model, (estimated 20% of the hull, the rest, I did myself)
