Adobe lines missing in AutoCad 2D drawing converted from pdf.

[richardBQKP2S]

A CAD drawing was plotted as pdf by others and thereafter marked up using Adobe.  When converted to AutoCAD .dwg drawing, the text is present, but the lines are missing. Raster option is on for the conversion. Is there a way to make the adobe lines appear.  They will appear when imported as an underlay but I need to have all the Adobe markups be present on separate layer(s) so the original CAD author can use them. on their drawings.

I assume when you state Adobe you're referring to Acrobat.

Perhaps Adobe Illustrator should be used instead which creates vector pdf.

Could you include a sample of this marked up pdf and point out the lines you're trying to convert back to AutoCAD?

This problem was given to me, so I don't know what software was used to create the original drawing.  But the pdf opened in Adobe Acrobat. see attached.

I forgot to say, those lines that are missing in converted file are those in color.

Unfortunately since those are markups made in Acrobat, they're not going to be recognized as part of the pdf.

One way would be to flatten those markups by printing to pdf printer again so they're converted now as raster.

Then import this newly printed pdf into AutoCAD:

This method worked.  I used Google Chrome to "flatten" the pdf and had a slightly different result from the file you sent in my duplicate post (sorry about that duplicate post).  The lines in the dwg converted drawing didn't have the double lines representing every Adobe Acrobat line.  The link you provided informed that the more recent 2024 version I have has the MARKUPIMPORT command with features to help with the tracing method I will be using.  The better way is to get the native files to work with and use the MARKUPIMPORT command when possible. 

Thank you
