Creating designs for cities all over the planet may have just gotten a whole lot easier - thanks to Brandon Liu, a Software Developer from San Francisco who used data from OpenStreetMap to create .DXF CAD files of 241 major cities worldwide. These files are entirely free to download, and from San Francisco to Sydney, Buenos Aires to Beijing and Helsinki to Harare, most of the world's major cities are included.
