I need help with 10.0 I need to calculate volumes at specific elevations 14.0 to -0.5 within 15 Sq. Miles with 5 defined basins. 9.3 had a nice tab in the 3D analyst pull down that gave us a word document detailing the cut and fill. This is all I need, not a new representation of the surface. I am basing all the calculations on a Tin surface.
