Question: can def be converted to dwg?
Answer: AutoCAD, DWG TrueView, and Design Review do not have a conversion feature to change DWF files into DWG format. ... There is a workflow that can potentially produce a usable DWG file from a DWF using the PDFIMPORT command in AutoCAD: Start a new drawing in AutoCAD. Use the DWFATTACH command and attach the DWF/DWFx file.
