This Natural Regrade drop-down menu command is used to calculate the cut and fill volume difference between the GeoFluvTM design surface in the drawing and another surface, the Comparison Surface. The Comparison Surface is specified on the Output tab. Possible sources for the Comparison Surface may be pre-disturbed, such as the natural landsurface or an earlier reclamation design, or may be disturbed, such as a mine pit or construction site.
If the valley bottom or GeoFluv Boundary polylines have been moved, or any setting in the GeoFluv project has been changed that can affect volumes, then the design surface in the drawing will be out-of-date. The "Draw Design Surface" button must be used to create a new surface in the drawing to reflect the changes.
When the user clicks on
the command, a dialog box appears with the
cut and fill required to transform the first surface into the current
design surface (layers GF_Channels and GF_Ridges). The first
surface is the Comparison Surface. The cut and fill are calculated
wherever the two surfaces
overlap unless an inclusion polyline is given in which case the cut and
fill are calculated within the inclusion polyline.
The results are displayed in cubic
yards in the English system of units and cubic meters in the metric
system.
