Cut/Fill Contours

This command displays the amounts of cut and fill between two surfaces by computing and displaying cut/fill contour lines representing the amount of cut or fill along that line. Cut contours are displayed in red (with negative values), fill in blue (positive values), while the lines of zero cut (the "daylight" lines) are displayed in green ("0" labels).

The Use Color Ramp option changes the color of the contours to be darker as the cut and fill get deeper. Use the Draw Only Cut/Fill Daylight option to draw only the daylight lines, indicating the areas where the two surfaces intersect. The Daylight Tolerance setting controls which contours are drawn in green.

Cut/Fill Contour Settings:
You set the contour settings in the opening dialog by selecting the Cut/Fill Contour Settings button, which is comprised of the Contour and Labels tabs identical to those in Triangulate and Contour. Please refer to that command for details on the dialog options. You may wish to designate alternate layer names for these sets of contours to avoid overwriting previous contours on surface layers, and generally you will set the contouring interval to 1 foot.
