Thanks for quick reply, but this is what I have done.
I wan't it thinner? Is there an setting to control that?
If you save the IDW as DWG an then print to PDF the lines are thinner, so I think it is an Inventor setting
I am not too sure, I only use dwg's, maybe someone else has some expertise in this area. That check box is what I use to control line weights on pdfs.
