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 6WDNH &3 ! to begin locating the catch points.
Staking the Catch Point
16. If the first button is set to $XWRPDWLF 6ORSH (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
)RUFH &87 6ORSH or
)RUFH ),// 6ORSH respectively.
17. The second button is used to toggle which
information is displayed in the lower corner of the
screen. You can select
9HUWLFDO 0DS ,
+RUL]RQWDO 0DS , or 6KRW 'DWD .
Note: You can tap in the graphic portion of the screen to
open the graphic in a larger window.
18. With the rod in the general location of the first catch point that
you want to stake, aim toward the prism and tap
6KRW. The
distance and direction information will be computed and
displayed along with other information pertaining to the shot.
The routine automatically determines if you are staking the left
or right catch point by the proximity of the rod.
