A FREE subdivision modeler. Highly intuitive, quick modeling.

Wings3D is an awesome little piece of software. It has a number of tools that I wish other, more complete, 3D apps had. It seems at times like the program was designed to work the way a designer might think.

It takes some operations that require 2, 3 or more steps in other apps and reduces them to one.

Excellent program. I keep it on my system at all times.
