You can do quite a bit with Poser primitives, like the 2 images here. But I only made these before I was pointed towards Wings 3D. WAY more possibilities :o).

Flat planes and boxes have basic square UV mapping, as do cylinders. Cones and toruses can be a bit tricky if you are just trying to put a simple texture on it.
