I used OpenSCAD to create a map of Manhattan. It shows the live location of subway trains. It was surprisingly easy, I struggled a lot with OnShape and Fusion360 trying to do this because there were too many polygons.

I found that starting with an SVG and extruding from there is perfect in OpenSCAD, but I’m sure I’m underutilizing it a lot.

I wrote a bit about it here if you’re curious https://hackaday.io/project/202488-manhattan-subway-map/deta...
