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). You
have the option to draw only the daylight lines, indicating the
areas where the two surfaces intersect.
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.
