DWF to AutoCAD drawing (DWG) converters do exist.
 |
An AutoCAD drawing uses floating point doubles. A DWF uses 32 bit integers. You will lose precision and to that extent - accuracy. Converting a DWF to an AutoCAD drawing is the equivalent of scanning in a plot and tracing over it. |
With the advent of the DWF Attach command in AutoCAD 2007, this question is likely to come up again. The topics of DWF precision and DWF Security have been covered by Brian Mathews in Shaan Hurley's Between the Lines Blog. For simple DWF files, 32 bit integers may be sufficient; however, there is a strong relationship between the "vector DPI" used to generate a DWF file and its resulting precision. This is evident when measurements are taken using Autodesk Design Review. This relationship has been documented in a table for imperial users as well as a table for metric users.
