The Depth from Hinge check box controls how the depth of the ditch is
measured. When this option is selected, the depth of the ditch is measured
down from the top of the ditch foreslope. When this option is cleared, the
depth is measured down from the finished ground centerline reference point.

Base elevation: Enter the true elevation of the bottom of the ditch. If you
use this option, the elevations are usually retrieved from the profile using the
Attach profiles option.
n
Base Width: Enter the width of the bottom of the ditch.
NOTE
You can only use two of the ditch parameters at a time (except when the
depth from hinge is selected, which makes three items selected.) If you
enter less than two parameters, ditches are not applied. If more than two
options are selected, then a warning message will be displayed and you
need to correct the situation. The command calculates the other
parameters automatically.
