In such a situation, rebuilding each of the surfaces will cause the other one to become out of date. Edit the grading to 0. Expand the Definitions section. Issues can occur as a result of circular dependencies if feature lines that are relative to different surfaces are then added as breaklines or boundaries to each other’s surface definitions. Just saying. If this is the case Civil 3D has tools that make creating a surface from 3D faces or 3D lines representing a TIN both accurate and easy. As you probably know, the ability to assign elevations from a surface to a feature line has been in Civil 3D for some time. That doesn't mean it's not possible though. Things have changed and you need to recalibrate your skills.
