It is a well known trick that you can export a PDF to DWG by using Adobe illustrator. This is achieved by opening the PDF and then choose export and export as a DWG, assuming the PDF contains vector linework.
However, can you do the same with a DWF file?
Technically yes, there are various tools and plugins which will allow you to convert a DWF to a DWG, but you will have limitation in the quality of the linework. However, you may have some success if the DWF contains vector linework with one of the following:-
- You can open the DWF in Autodesk Design Review, then PDF it using acrobat writer, then convert the PDF as highlighted in the technique above, using Adobe Illustrator.
- Alternatively, you could open the DWF in Design review, choose Copy to the clipboard, then in AutoCAD, choose Paste Special to copy the elements into AutoCAD.
- You will need to scale up the resulting DWG in both cases and the quality will be very low, but it should be enough to start a basic schematic plan from.
