I am presently doing a small addition and renovation to an existing farm house. Everything seem to be fine (with the exception of the exterior step issue). I have managed to nicely delineate between the existing and new construction at the main floor level. However I have tried to do the same on the second level - existing walls do not want to grey out (half-tone) when I refer to them as existing. Why - existing walls can not be on multiple levels ???
