A CAD and a rendering program have very different philosophies, so I'll show you
how my exporter works with a small example. It only translates simple faces and
lines. But I have a trick. Very simple and fast blocks in CAD, which they call
most useful blocks written for POV.
Instead the export for STL I need just to build the blocks (inc) to give to POV
making and testing the future inc files for my lib.
STL uses only faces, and therefore it is very suitable for helping CAD.
