how to export cad to pdf in black and white

It seems like this should be really simple to do in Adobe. If I increase the resolution, then it sometimes will say that the image is too big and in cannot save/export the image.

I've also tried exporting the PDF to a raster format like TIFF but the resolution is really bad for engineering drawings. I've tried importing into my CAD tool, however all the fonts are different. I do not have AutoCAD and use ProE/Creo instead. I've tried using custom Color Plot Styles (monochrome.ctb) and Named Plot Styles (monochrome.stb), but since I did not create the original AutoCAD DWG (it is 10 years old from 2004), they are not the correct plot style files. I've tried outputing the color PDF to a post script file, however that is still in color. Thanks again for your answer, I hope the wizards at Adobe can come up with a good 's not a big feature, but a simple one that could save me a lot of hassle here and there.I am also having trouble with converting AutoCAD DWG to Adobe PDF.

In this case I'd be willing to sacrifice a little quality.the same trade off as converting the PDF to grayscale in Acrobat Pro would be fine by me. If I could just export that same ID file as a grayscale PDF I'd be done. We do an ad for a magazine in color and then they say 'hey, can I have this in black and white, we're going to run the same ad in a newspaper'. But what I'm really craving is the quick fix for a document that is done in color that a client now needs in grayscale. In a perfect world when I design for black and white I carefully convert every image and balanced them as needed and build the InDesign document as a grayscale doc from the beginning. I agree with you whole heartedly about the sensitivity to different colors when converting to grayscale. Dov, thank you for your well thought out, and correct, response.
