As far as I know, it’s still used in Autocad. We used it to customise Autocad for our clients – an example is that we had Lisp routines to automate the layout and manufacture of wiring harnesses/looms for small volume car manufacturers and renovators. The operator would set ‘pins’ at various locations in the design and then be able to route the various cables.
Once the loom was finished, an A0 (pen!) plotter would print out a full size sheet with the pins and cable routes marked. This would be tacked onto a sheet of plywood, the pin locations would have nails hammered in and the layout of the wiring would begin.
This is before Windows days so a LONG time ago. God I feel old now!
