What happens when you create the detached surface? Does it work at all?
I ran into an issue where I was using a grading group to create a berm, then
creating a detached surface, and pasting it back in. That essentially
created a null solution for the grading group, causing some issues. I don't
believe it was addressed in SP2. For now, after you create the detached
surface, delete the grading group, and it _might_ work better. This method
has worked for us.
I know not ideal. 2007. I'd bet on it.
