POV Ray aka Persistence of Vision Raytracer is a high quality rendering program. It uses scripts to describe a scene and renders each ray of light that makes up the scene. It is not a modeller.
If you want the CAD-like experience with POV Ray, check out programs like MORAY.
Depending on your needs, there are several cheap modelling programs out there. One of my favorites is Metasequoia LE.
