MaxView does not presently automatically calculate volume, however, you can easily measure an area displaying the area in Square Yards.  If something is to be applied to that area to a uniform depth, the volume can easily be calculated by multiplying the Sq. Yardage by the depth in yards.  For example, if the area shown below is to have 4” of topsoil applied, the cubic yards of fill required is 622 * 4 / 36 = 69.1 cubic yards.
