Thanks! Though now I feel stupid. I thought that I had something going with that cutaway, but turns out, my scale is entirely off. Further research has proven that the bridge module is indeed THREE decks high (but deck 3 is half-sunken into the primary hull). Causes all sorts of problems for me, but I'm just glad to be getting a little closer to the truth here.
