I had to accomplish pretty much the same exact task circa 1999, but in Aldus Pagemaker using Postscript.

My first job out of college was a 6 month contact at a fairly small industrial control manufacturer that had been purchased by a larger conglomerate. All of their engineering documentation needed to be converted to the new company’s format.

The old company had devised a scheme whereby a wire harness could be completely described by the part number, which encoded the wire size, color, length, and termination. The new company wanted a detail drawing for each wire, with thousands in the database.

I made a library of reusable glyphs that could be stored in Pagemaker layers, and connected with postscript generated lines, and a script to iterate through the part number database and generate drawings.

Wire harness specs in part numbers - elegant. Same pattern, different purpose: you generated final documentation, we generated DXF that fed back into CAD workflows. And what's running on this page is the same - a real interpreter executing AutoLISP against JSON data, outputting valid DXF. Not a slideshow, a local data engine with demo data loaded.
