Converting PDF to DWG with autocad doesn't work as expected (SOLID instead of Lines/Polylines)

[guilherme.lepinski.sc]

I attached the file in question. In every way I try to convert, in various configuration, it still doesn't work.

The final result only comes with solid objects and not with lines and polylines as it should be.

Forgive me, but can you explain the differences that you do not wish to have? I'm not sure I understand, sorry

I suspect you are referring to vector PDF creation? if you did not use "microsoft print to pdf" your issue might just go away: If I may ask, how old an AutoCAD version are you using that it does not have built-in PDF drivers?

Hi @pendean, thank you for the reply!

My Autocad version is 2021.

The problem is simpler than it looks.

I am using this to convert pdf to dwg, as I always do:

But it converts the lines in the PDF to solid objects:

So, instead of a drawing composed of solid objects (as you can see in the image), i need it made of lines and polylines.

Those are not solids, Those are hatches. 

The original PDF probably has them as 'hatches' so that is the way they come in. 

Do you have access to the original file that was used to create the PDF?

Hi @TheCADnoob, thanks for the help!

I don't have access to the dwg file that originated the pdf, it's a catalog of a product.

But what you said makes sense, probably there is no other option if the original one was made with hatches.

Thx anyway !!!

Glad to help and sorry it wasnt better news. 

I verified with another app. Your PDF has the content in that format, its not line work, its hatches. AutoCAD is importing as intended. 

I opened your PDF in Inkscape and selected the line and you can see there are three nodes on the end of the line, indicating that there are three sides to what looks like a line. For comparison, I opened a line work PDF and selected the line and you see only 1 node which means it's actually a line.

DWG to PDF then back to DWG conversions are at best a shaky prospect to rely on sadly. And relying on the very basic built-in tool is probably not the best if you need way more control. I suspect you will need to purchase a 3rd party better quality converter.
May I ask why this is three-way-conversions a business need of yours? I'm curious more than anything.

EDIT: I assume you do NOT actually have the original source DWG file, is that correct? Then ask the PDF creator for a DWG or DXF if you can, it is the better approach.

Hi @pendean, you are correct. It is better to look for the original dwg file.

Thanks for the help !
