I can think of a few ways to build something like this from Poser's primitives and the grouping tool, and a whole lot of export and import, but my gods that would make me want to eat my own face off if I tried. And 2 years later I'd probably only be half-way up the leg. Most I've ever done with building in primitives is some of Dr. Geep's set tutorials. They're all mostly resized squares and some cylinders here and there.
