Found this nifty tool… https://cadmapper.com/
More info: https://www.archdaily.com/535628/free-cad-files-of-241-major-world-cities
Exports .dxf files with a wide variety of settings. Seems to crash AI when loading the .dxfs, will need to try with AutoCAD when I get back to work. Seems pretty cool though and lots of applications for GF if when can figure out how to handle the files.
