Sketches

I have decided to go with the 3D option, but use Blender to pre-model pieces and intelligently arrange them in Processing. 3D geometry generation is a major thing to get to grips with, and there are many things even beyond basic meshes that I very much want to do, like bolts! How would you drill a nice hole in a mesh for a bolt? Doing my own boolean mesh operations seems a little outside scope. So, pre-modelled geometry it is. I remember something about OBJ importing support in Processing, so I must test that soon.

Here are my sketches so far.
