Creating quick and Dirty Complex 3D Models...?

I know I could use NURBS to do this, but seeing that I’ve never done any 3D complex objects, is there a quick and dirty way of creating say a simple submarine with a mast, balancing rudder and stablizer fins? Because I’ve looked at NURBS and it seems a little confusing to me.


Nobody knows…?

Creating complex models by hand is a nightmare, one number wrong and its chaos.

Have you tried using a 3D modeller and converting to C code, or at least to a format?
