This tutorial demonstrates how to create a composite volume surface from a base surface and a comparison surface, and then perform composite volume calculations.
A volume surface is similar to other surface objects, in that you can display cut and fill contours, cut and fill points, add labels to it, and add it to a project. The cut, fill, and net volumes are properties that can be viewed by selecting Surface Properties.
The composite volume method uses the points from two surfaces, as well as any location where the triangle edges between the two surfaces cross. The cut, fill, and net volumes are calculated based on the elevation differences between the two surfaces.
