When I was here last time I was contemplating does the WIP represent where the Structural support beams, girders an Keels would be.
i was working on a construction profile of that sort myself, my biggest pet peeve was always that concave lower portion of the saucer... it may be an iconic portion of the ship, but as a designer i always saw it as a gigantic waste of space!
i was already deep into my own project when i discovered CTM's endeavour. and decided to put mine on hold and see how his turned out first...
on that note, Its looking great! glad to see you're back into this beast!!!
