We have started to better document our Civil 3D entity references and it would be helpful to be able to search and replace areas where there are text-based identifiers in Civil 3D objects. Some examples with surfaces are the CIvil 3D object's description, the breaklines, and the boundaries.
We were using the layer name as the identifier for the breaklines and boundaries when the client decided to change the standard we were using for our naming convention, requiring us to track down and rename everything by hand. If there was a search/replace this would have helped save time.
