Opening and editing a CAD file shouldn't cost about $2,000 a year per seat, or be tied to a Windows machine. Reading and redlining a drawing is the most common job on a project, and for years it was locked behind one desktop seat. We built CAD Editor to open that up: open any DXF or DWG, on any device, in any browser, free, with the familiar shortcuts you already know.
