OK, thanks, this is starting to make sense. I've avoided the issue until now, but I need to access some Civil Design components (Pipes, etc.) -- preferably in the 2006 interface. As an ADN member, what do I need to do to access Civil Design? (I have an item for the Civil Design workspace in LDT 2006, but nothing happens when I click it.) Do I need to access Civil Design through Civil 3D?
