unlike ape you figured it out! yes it does
and indeed had the idea of having it look battle-shippy while still retaining that functional White-ish NASA look and keeping it realistic with the centrifical force gravity thing.
You DONT do what I complain that whomever designed the Enterprise GT did. You dont add "doodads" to your designs which arent somewhat functional. Every detail of that design looks like it is needed. You did not skin every surface of the ship and enclose the complete structure, and you would not have to. Love your design.
