I am making pdfs out of Autocad 2008 Electrical dwgs. When created they appear as the colors on the dwg. Is there a way to create them so the pdf is in black and white? I seem to remember when I first started creating them, they were created in black and white. I am wondering if a setting got changed.
This is not a color management question but an application-specific issue. I would inquire at the Autocad software web site or at thew Adobe Acrobat forum for your specific platform, Macintosh or Windows.

I'm unfamiliar with Autocad 2008, but you could try converting these files to a grayscale profile inside of Acrobat. Inside the Acrobat menu, go to:
Advanced > Print Production > Convert Colors...
Then check on the check box in the Output section of the dialog that says "Convert colors to Output Intent". Next to this there's a drop down menu labeled "Profile:". Use this drop down menu to select a grayscale profile (these are listed as the bottom of the list as "Dot Gain xx%" or "Gray Gamma x.x"). Gray Gamma 2.2 might be your safest bet. Unfortunately this action is also undoable in Acrobat, so you'll get a warning for this after you hit OK in the dialog. If you don't like the result I think you'll have to close the document without saving and then reopen it to try another profile.
