Remove the layer information from Adobe PDF

Question

I make lots of drawings in AutoCAD and convert them to PDF and pass it on to the client.

What I do not want the client to see in the drawings, is the different layer information that PDF is offering.

I'm using Adobe Acrobat 9 on Windows-7 so I will be able to edit the PDF files.
So far I have seen options in AutoCAD using which you can suppress the layer information from being passed from AutoCAD to PDF.

The concern is for the files (100's of them) that have already been converted into PDF format. Is there a way to remove layer information from them?

Answer 1

This may be a bit late.

You can change the settings before printing to tell ACAD not to include layer information. Go to Plot, Click properties for the PDF printer you use. (I use DWG to PDF) Click custom Properties, The custom properties at the bottom of the Tab. Then Additional output settings untick "Include Layer information" I also tick Capture all Fonts to avoid any compatability issues, but this may increase the file size slightly.
