Any idea how hard is this going to be? Basically it needs to identify
features (holes, edges, etc), then project these features to an
orthographic plane, alone with associated dimension
As I understand it, this is a Very Hard Problem. This is (one of the
reasons) why there are so few converters from POV-Ray to mesh-based formats;
it's highly non-trivial to tesselate CSG.
POV-Ray is pretty fast. I had contemplated just rendering a bunch of
POV-Ray images to emulate a realtime 3

I don't know if it is CSG, but in the TeX world there is Gene
Ressler's 3D modelling program Sketch that generates

If the purpose is just to visualize the model then there are easier
ways to do so that generating a polygonal representation and rendering
that. See these for more info:

Mecha [1,2,3] is a constructive solid modeling DSL. I haven't worked
on Mecha in awhile, so this release just contains some minor cleanup
and reorganization.
My next step is to build an OpenGL interactive visualization tool,
something like a basic CAD window to rotate and zoom around 3D models.
