When we install a Country kit (for a country) then C3D gets some files (*.codes).
Generally it works fine but if someone has a drawing without a Country kit (in english) and I open that drawing in my C3D (with Country kit for Spain) then I can´t see slope patterns due to the slope patters where defined with FL (codes in english) and Civil 3D wasn´t able to translate it to spanish.
The same happens with "Quantity takeOff Criteria". If the first user did a Quantity takeOff Criteria with structures (shapes) those shapes were in english codes. Civil 3D can´t translate those codes to spanish codes so the result volume tables for that codes will be 0. (0 volume).
Moreover, Civil 3D does not throw any warning about this.
