Use Autodesk DWF Viewer, a small, free, downloadable application, to view and print DWF (Design Web Format) files. Imagine a digital design file so smart that it contains information about measurement, location, and properties of objects in the drawings. That's what you get with DWF, a fast, efficient, compact format designed for electronically distributing rich design data to anyone who needs it. And with Autodesk DWF Viewer you can get all that data?or just what you need?for free, without having to learn or purchase the software that created it. DWF?intelligence you can see.
