Major update 9-20-07 I'm changing this thread to include architectural meshes from all my Starfleet projects. Today, I'm adding the architectural set from the Olympic Class starship I built (It's on the queue, look for it in a day or 2) This includes the upper dome, lower dome, nacelle, and walls that match the extra texture maps. All the meshes work like columns. I did a 'classic' recolor so any ambitious shipbuilders can make a Daedalus class starship.
This set came about when I was trying to build a Constitution Class Refit. You can make a decent facsimilie of certain things ingame, but there are some shapes you just can't make ingame. So I built 4 new meshes, specifically for this ship, in blender. (This upload is a teaser, the ship is still on the moderation queue).
The nacelle, warpcore, and sensor array are cloned off one of the base game columns and can be found under Build Mode/Miscelaeneous. I tried to make the deflector dish work like a window, but it wouldn't cooperate. So I cloned it to a painting. It's in Decorative/Wall Hangings.
It took me a while to get all the meshes and texture maps right.I hope you like.

Polygon Counts:
Nacelle: 18
Warpcore: 276
Sensor Array: 360
Deflector Dish: 200
