Thanks but I've already been doing that all morning. There are no differences unless they are hidden settings locked deep in the drawing file somewhere. The surface won't even show up if I create it again from scratch with a different completely brand new surface style either.
Sad that it's 2013 and Civil 3D still has this problem. I just did a Google search for invisible surface, didn't realize the date of the original thread, saw that someone solved their problem but never stated how they solved it.
Thank you! Jeff M! That was exactly what the problem was! Not sure how it could have ever been turned off as no one here would even know where that setting would even be! Case closed!
