As more people become familiar with Autodesk DWF, the design publishing format Autodesk created as a design-specific alternative to PDF, there arises a need for specialized tools. If you have been sent a DWF file for a project and really, REALLY need a DWG, take a look at Any DWF to DWG Converter, from AnyDWG.
I say "really, REALLY" because many times users just assume they must have a DWG when there is no compelling reason. But if you know need from habit, give the software a look. You can read more about it in the TeamDWF review, "
Any DWF to DWG Converter By AnyDWG Does the Trick."
