Open DWG Files Without AutoCADFree, No Software to Install
You don’t need an AutoCAD license to view DWG files. Open, measure, and convert drawings for free — right in your browser.
Why You Don’t Need AutoCAD
AutoCAD costs $1,975/year for a standard subscription. If you only need to view DWG files — not create or edit them — you don’t need that investment. Free viewers can open, inspect, measure, and print DWG drawings without any Autodesk software.
This is especially useful if you’re a contractor, project manager, or client who receives DWG files from architects and engineers but doesn’t do CAD work yourself.
