The title says it all - when plotting directly to the Adobe PDF driver from within AutoCAD 2010 on Windows 7, it just errors out or shows nothing at all. If we use the Adobe PDF.pc3 driver, we get the same problems. But, if we use the DWG to PDF.pc3 driver, it works okay.
When testing the same setup in AutoCAD 2011 on Windows 7, all three options work fine. Has anybody run into this? Any ideas how to make it work on AutoCAD 2010?
