14. The Segment # (Fill HP) field is used to select which
segment to compute the slope from in a fill situation.
This is useful when your road profile includes a ditch and
you are staking an area that requires a fill. In this
situation, the ditch would not be necessary so you have
the option to compute the slope from Segment 1. (See
illustration.)
15. Tap Stake CP > to begin locating the catch points.

16. If the first button is set to Automatic Slope
(recommended), a cut slope will
automatically be selected if the hinge point
is located below the surface of the terrain
and a fill slope will be selected if the hinge
point is above the terrain. You can also
force the computed values to be based on a
cut slope or fill slope by tapping the button
until it reads
Force CUT Slope or Force FILL Slope
respectively.
17. The second button is used to toggle which information is
displayed in the lower corner of the screen. You can select
