The Cube was a gift, and the PS work didn't go that far.

I found PS pretty inscrutable, esp. the function-filled variant used in Virtuoso, but did manage to get dimension lines coded up (which promptly ran into precision problems which I eventually gave up on).

OpenSCAD is a lot more approachable, and METAPOST was easy to pick up and make use of:

Still working through this at:

and mostly using visual tools (which arguably is limiting me) https://www.blockscad3d.com/editor/ and https://github.com/derkork/openscad-graph-editor and of course, had to throw: http://pythonscad.org/ into the mix. Still a bit miffed that Nodebox and Processing or maker.js weren't a good fit.
