This command calculates the cut and fill volumes between the surface modeled by one grid (.GRD) file and a constant elevation or value. This is the same as Two Surface Volumes except that the second surface is a flat plane at a constant elevation instead of a 3D grid surface. Please read that section too for additional descriptions. If the grid contains grid cells that have no elevations, you have the option to extrapolate elevations from the grid cells with elevations. When you choose not to extrapolate, no volume is calculated for these grid cells. There are also options to specify inclusion and exclusion areas. When inclusion areas are specified, only the volume within this inclusion area is calculated. Volumes within an exclusion area are not included in the calculations. Inclusion and exclusion areas are represented by closed polylines and must be drawn prior to using this command.
Select the Inclusion perimeter polylines or ENTER for none:
Select objects: press Enter
Select the Exclusion perimeter polylines or ENTER for none:

(Yes/<No>)? press Enter If you enter Yes to this
prompt,
surface elevations will be computed for any grid cells that have null
elevations.
Enter the base elevation: 570
This defines the second surface.
