City CAD files for download
I've published a simple web page with 241 metro extracts in .DXF format. The source is the Mapzen Metro Extracts that I downloaded a week ago, so they won't be magically updated every week. In total they took 12 hours to generate on my laptop, and clock in at 3.5 GB unzipped. I did some testing on Mac and Windows, ruled out the bzip2 compression format 'cause Windows doesn't like it, and was successfully able to open files in Rhino, AutoCAD, and Revit!
