This command creates a spoil pile at a target volume or
elevation. There are a few design methods. The Perimeter Polyline
method takes a 3D polyline outline of the top of a spoil pile and
adjusts this polyline by either changing the elevation or extending
a side to reach a specified volume for the pile. The resulting pile
is drawn as 3D polylines showing the side slopes and where the pile
ties into the existing surface. The Cone methods take a single
point and slope to build a spoil cone. The cone can be sized by
either target volume or by height.
As the program runs, it will seem to draw several piles as it
tries to find the target volume. The resulting volume will not
match exactly the target volume but will be very close. The smaller
the grid cell size, the closer it will be. This difference is just
to save processing time.
