This is going to cause me (self-induced) trouble, because I’m going to have to accelerate some planning of mine trying to get accurate info out there. As far as I’m aware the TOS sets were all done off a few existing plans, some info from production personnel, and the accrued insights of ardent fans building and drawing things over and over through the years. That is until recently, when set elements were more available. But they weren’t built from photo-matched 3D models, which is where you can derive the most accurate info. The TNG sets, more than most, demand that type of approach even if they have access to more original blueprints than are currently available to fans (hopefully Paramount archived that stuff, and didn’t let it disappear who knows where.)
Hmm… going to post something soon on this.
