I have alot of old 2D drawings on paper, which I am in the process of scanning & saving as pdf files. Is there any way to convert these scanned pdfs to dwg format? I have tried AutoDWG but it only works for original pdf files not scanned pdfs. Any suggestions would be much appreciated.
Thank you

Judge, I'm using AutoDWG, and I'm converting raster to vector. You may check the version you are using as there are 2 versions of the PDF to DWG converter from AutoDWG. You may download the stand-alone version (http:/ /www.autod wg.com/pdf -to-dwg-co nverter/do wnload.htm) but not the plug-in version. The stand-alone is featured with conversion from paper to DWG.

RE: Convert scanned paper to DWG
Many years ago I was fortunate to be able to use a really good one, that converted to about 80% accuracy. I remember we had lots of gaps and squiggly lines until we guessed that we should use the center-of-line conversion option instead of the boundary edge (default)option because the latter gave dual squiggly lines at each edge of the original raster line. Once we did that, and realized that circles were NOT circles, and text was NOT text, but derived line segments we were on our way !
I'm aware that there have been advances since then, especially in the area of optical character recognition, but you're still probably going to have to do the last 20% or more by hand. The input that program accepted was only either JPG or BMP or TIF, but you should be able to jump that hurdle if it still exists. Yes, drawings that were CAD and written out to PDF are easy to back-convert, but that isn't your problem. Yours is a bit more complicated. But the solutions are out there. Try some free-to-try commercial programs, and BUY a GOOD one. Not cheap, but WORTH it!
One suggestion tho- the one we were using also had commands that allowed editing the raster file as if it were a CAD drawing. Pretty cool! Eventually in use, all our raster drawings grew into true CAD drawings, and they were usable right from the start in AutoCAD, even those that hadn't completed the conversion process ! If I can discover which program that was I'll add the name of it to this thread. I hope I've added enough clues tho to help you solve your mystery !
Good Luck !
