Automatic cut/fill optimization

Select this checkbox and enter the percentage difference between cut and fill volumes to have the terrace automatically lifted or dropped and recalculated in order to balance cut and fill volumes. Balancing will stop when the percentage difference is less than the specified value or twenty attempts at balancing have been made without reaching this value.

Compaction factor

Enter the factor to apply to cut material before being used as fill. A factor of 100 gives no compaction, less than 100 gives compaction, and over 100 gives bulking. Note that this entry is not used during the balancing calculations but is used when the final volumes are reported.

Topsoil to strip

Enter the depth of topsoil to be stripped from the terrace before fill takes place. Note that this entry is not used during the balancing calculations but is used when the final volumes are reported.

Use exclusion polygons

Select this checkbox for the volume optimization calculations to ignore predefined PolyFences. You will be presented with the Select Polygon(s) at a later stage in this routine to select those PolyFences.

Volume report by Band or Prism

Select the required option. See the entry on Band vs Prism vs Contour Volumes for details on the various options.
