It would be great if Scene Viewer could include a 3D volumetric calculation tool like the one in Site Scan. I am referring to the tool where you can delineate a 3D polygon on the model surface and this clips that portion of the 3D mesh and interpolates a surface beneath the model surface. Volume calculations are then provided for the difference between the top and bottom surfaces. If this is done around a stockpile for example, the model surface is the piled material and the interpolated surface is the ground beneath the pile. Also having the ability to choose how the base surface is interpolated is a great feature the Site Scan 3D Volume tool has.
