@Mytran - I think for now I'm going to stick with 355m for the TMP Enterprise.
I used the orthographic views of the Director's Cut Enterprise from Doug Drexler's site (wish I had a high res version
) to do some lining up and comparisons.
There is a scene in TMP where the travel pod docks to the Enterprise and interestingly, that close up is kinda flawed. The windows next to the docking port are much closer than they are in the model. And there must be some kind of magnifying effect going on with the head at the window as he doesn't look he would fit through the door
Anyway, at 305m, a 6' person sorta fits through the docking port while scaling up to 355m a 6' person nicely fits through. Plus, other internal sets fit better as well.
The other thing I noticed was that at 305m, it seems that the TMP Enterprise's primary hull was thinner than then TOS Enterprise which seemed really odd.
