You should print that CAD file as a PDF so the non-cad people here can view it as well.
I have the capability if you need help.

edit:
missed your last post. What do you mean you used the layers and it would be useless as a jpeg? As in if you just did a screen shot?
You should still be able to print it to a PDF or TIFF using your pen table and have it look correct. Or even do a print preview and take a screenie.
If you need help lemme know.
