You can draw the edges as lines.

Not that I know of.  The distinction would be whether you actually build
the objects.  Certainly for something like this you would be working
with something like a "faces" object rather than a fully 3-D object.

You can generate POV-ray source.  This is not a system for creating
beautiful pictures, but rather a great 3-D sketch pad.
