Here are two ways to convert PDF documents into .DWG (drawing) files.
These are in fact free and they do a great job for the price. They both work the same in that the free versions will not process layer information if it is included in the PDF.
These converters are great alternatives to buying a full product that is dedicated to doing this and if you rarely need to convert a PDF to CAD these are especially great.
Both of these converters use your email address to send the file to you when it is finished converting.

One thing to note: Cometdocs has a cool feature that lets you register with them (for free) and this will allow you to store your converted documents on their server and have access to them wherever you have internet access. Otherwise, the files get erased after 24 hours.
Plus Cometdocs doe s a great job of retaining Text
AutoCAD Tips 
Hi, maybe you could try out VectPDF which is an autolisp front end to pstoedit & GPL Ghostscript for converting & inserting PDF inside AutoCad. Just select a PDF file & insertion point. It’s completely free.

Aide Converter (http://www.aidecad.com/pdf-to-dwg.html) converts 60 PDFs to DWG/DXF format for free.
Thanks for the link, i will try it soon

AutoDWG free online conversion also can do that, you can visit http://dwg.autodwg.com/
The key to success with PDF files is to determine whether you have a vector (computer-generated) or raster (scanned) PDF file and then choosing the right tool.
Spotting the Difference – Vector and Raster PDF

There’s a new pdf2AutoCAD plug-in for Autodesk 2012 and newer ($59) that lets you open an editable PDF via command line or the menus . For older AutoCAD programs and other brands, there’s pdf2cad ($195 – download a free 30-day trial and get a coupon for $129). Both will open and edit a computer-generated (vector) PDF file in AutoCAD with layer support, rotation, object recognition, etc. It’s not designed for scanned drawings (raster PDF) and is limited to producing a PDF underlay for these raster PDF files. It’s not free but has a committed engineering team who’s been developing and refining it for almost 20 years. It pays for itself after the first conversion with the time savings.

If the PDF contains raster image, you are dealing with Raster to Vector, if the PDF contains vector, most programs will be able to recover the data. We use Any PDF to DWG Converter and you can download a free trail version from http://anydwg.com/pdf-to-dwg.html
convert pdf from autocad?
Within the post found here there is a script file and also batch routine method to plot to PDF.

here is a separate application that plots to PDF

Is it possible to change the text PDF to Blocks DWG ?
The lines and circles work great
Not that I am aware of. There have been some changes to online PDF converters since this initial blog post and each converter seems to handle text differently.
Instead of using online converters we can also utilize the builtin PDFIMPORT option in AutoCAD. It is available in versions above 2017.
If you have an older version of AutoCAD, there’s a plugin you can use https://visual-integrity.com/products/pdfin/. There’s version for AutoCAD 2011 and earlier and another for 2012 and higher.
Cool!
Thanks for the heads up.
