I am Going throw the Tutorial on Generating Surface Volume Information but cant help but notice why they have inserted Berm Breaklines.dwg. Since i also want to find the Cut and fill data to level my Site should i use the same Breakline.dwg or made another one for myself and how?
I am learning from "http://docs.autodesk.com/CIV3D/2012/ENU/filesCTU/GUID-20DD4422-EC0D-4537-870F-96C62AD6679-60.htm"
I believe the drawing you are inserting is just data. So, for your site, you would need to create your own breaklines and then add them to the surface (in the tutorial, instead of creating breaklines, you are inserting them from a different drawing, not really a real world work flow in my opinion).
