Catch Point Hinge Point
(Segment 2)
A road with a ditch requiring
a fill and the hinge point is at
Segment #2.
Fill Slope
Hinge Point
Catch Point
(Segment 1)
A road with a ditch requiring
a fill and the hinge point is at
Segment #1. (The ditch is
ignored.)
14. The Segment # (Fill HP) field is used to select which
C L
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.
