Autodesk DWF Viewer (ver 6.5) Abandoned Freeware The Autodesk DWF Viewer allows you to view and print 2D and 3D drawings, maps, and models saved as a *.DWF (CAD) file. Note: Versions 7.x are critically buggy, and were soon abandoned in favor of Autodesk Design Review. Therefore, version 6.5 is the preferred version.
