We need to convert PDF to DWG quite often, can anyone recommend good convert tool?
Answer - If you have a CLEAN line drawing only available in PDF format, you can convert this to Autocad dwg using Adobe Illustrator. Open the PDF file in Adobe Illustrator then do a File, Export, save to Autocad dwg selecting 2000 version. That’s it. When you open the file in Autocad, you will need to check the scale of the drawing and work on the layers since you will lose this information.
