Hello

I am looking for a solution to transform/digitize a file.pdf
and transform it into .dwg or .dxf format
With free software if possible

Thank you

You type " convert pdf to dxf online " on google and there are many online solutions to do it

Thank you for your feedback

That's what I did
I've tried several apps, it doesn't work well, the lines are transformed into a sentence with special characters.
I'm looking for a more reliable software! or the result will be great

Thank you

The top quality also depends on the origin of the pdf. (Scan export software...)

Hello

To convert a PDF file to a DWG or DXF file in AutoCAD, the usual method is to use AutoCAD's PDF import function. AutoCAD includes a command called PDFIMPORT that allows you to import TrueType geometry, fills, raster images, and text from a PDF directly into an AutoCAD drawing in DWG format. Once imported, PDF objects become editable as AutoCAD objects.

Here are the main steps to follow:

  1. Open AutoCAD.
  2. Use the PDFIMPORT command (or on the ribbon, Insert > Import > Import PDF tab).
  3. Select the PDF file you want to convert.
  4. AutoCAD allows you to choose which pages to import and which categories of objects to extract (lines, fills, text, images).
  5. Import and place the PDF content in your drawing.
  6. Then save the drawing as DWG or export it as DXF using the " Save As " or " Export " command.

Be careful, the quality of the conversion depends heavily on the quality of the initial PDF file and the type of content. Vector PDF files work better than image scans (raster PDFs).

For complex or heavily rasterized PDFs, some commercial third-party software may offer more advanced conversion.

You can find the command explained in the official Autodesk documentation and online tutorials dedicated to this function.

Not all software is of the same level, one of them had created lines
non-continuous, sort of poly line/curve, but not very usable.
I think the person had written a Word document for a quote by integrating copied views from a SolidWorks type 3D drawing
All saved in .pdf format for a customer

Thanks for the info
I forgot to mention that we were using the DRAFSIGHT software from Dassault
and not precisely AUTOCAD
I still looked at the possible formats for importing
is there DGN / SAT / DELMIA XML / 3DCC / SVG / HOMEBYME?
I hadn't found PDF (which on the other hand is feasible in export)
We also have edrawing possibly
Kind regards

Hello @olivierlorch

I guess you've already tried?

Little chance of obtaining a format that can be used in dxf if it is printed from an image then transformed into a pdf.
All the solutions online or via software work well if it is a drawing format (CAD or CAD) transformed directly into a pdf.
Otherwise it remains unusable or hardly usable unfortunately.

It seems to me that in this case, if the PDF is of good quality as said @Patrick_EMIN, the scan is of quality if the pdf is just as good.

The ability of software today even on free software, can get results. Especially since there is a need on this side, because many industrial sites in France, old ones, need to digitally reproduce paper plans.

I had tested this site before it became paid and it worked surprisingly well. But I agree with the others, you need a fairly clean image at the base.
