In the old days; average end area cut and fill volumes were calculated manually from paper cross sections representing a proposed roadway design. Today, using Civil 3D, we can extract average end area volumes with only a couple clicks of the mouse.
The key to calculating corridor volumes is found in Civil 3D’s sample lines. Sample lines not only “sample” drawing data, they can also leverage that data to perform volume calculations and then store those volumes as dynamic material lists that update whenever the corridor model changes.
If you are interested, I’ve created a quick video that walks through a workflow leveraging sample lines to calculate average end area cut and fill volumes from a corridor model.
