And hmm... I haven't thought of an overlay before in my rendering. I'll play around with it. Which schematics were you looking to have it measured against?
I was thinking about a new piece of work, combining the best aspects of the ships here
No hotlinking, just cut and paste>
On the first,
You notice the deflector dish pokes out a bit, but not as badly as on the JJ. So having a combination secondary hull with the TOS dish fore, but the TMP all the way back would look even more fluid. Imagine the outer-most line of each:
Now on the second.
I like the added length of the JJ shuttlebay to be taked on to the composite I suggested above, and to widen the saucer of the refit out to JJ specifications. Raise the refit naceles to where JJ has them (only longer refit nacelles)
And your end composite of the 3 connie type ships will be even more swan-like.
