Here it is: Crazy Sensor Combat Frigate Combat Ship. Or the TCS Exeter class.

Red Circles indicate where I am thinking of putting weaponry. It's anti fighter stuff, rapid firing guns...

Engines. W00t.

Profile view from the bottom of it.
All that stuff on the front are things like sensors, scanners, blinking lights, backup comms. The small tower on top of the bridge tower is the primary communications.
And that big circle thing is a dockpoint. Hopefully.

And, I dunno if this is a problem, but:
The program can only export it in the following:
.3ds
.dwg
.dxf
.fbx
.obj
.xsi
.wrl
it can save as:
.skp
Which one of those should I use?
