Well, I'm clearly going to have to step it up for my next batch of window boxes.
The saucer rim windows are going to be a real beast. The ship gets real cramped in that area, and the Rec Deck in TMP (the only part we saw on screen) just made the whole thing much larger than the scale of the rest of the model would imply. I ended up making everything 75% of its normal height on the assumption that the windows were small enough that no one would ever notice.
I figured if I ever did a "meant-to-be-seen-from-the-inside" movie-era Enterprise, I'd just not worry about reconciling the interior and exterior and scale the middle decks of the saucer to match the rec deck set. Make everything nice and roomy.
