Des. Slope is the design slope of the nearest cut or fill slope when
$XWRPDWLF 6ORSH is selected, otherwise it is the design slope of the
selected slope.
Obs. Slope is the observed slope of the terrain at the current rod
location computed from the last shot and the corresponding hinge
point.
Cut / Fill is the amount of cut or fill necessary for the rod to be on the
design slope from the current rod location. If this value is zero, you
have located the catch point, provided you are on the correct station.
Away (CL) indicates that the rod must move the specified horizontal
distance away from the centerline (perpendicular to the centerline
and parallel to the current station) to locate the catch point.
Likewise,
Toward CL indicates that the rod must move toward the
centerline by the specified distance.
On Station indicates you are properly aligned on the current station.
Back Sta indicates that the rod must move back toward the start of
the alignment (parallel to the centerline) by the specified distance to
be properly aligned over the current station. Likewise,
Ahead Sta
indicates that the rod must move away from the start of the
alignment to be positioned over the current station.
The remaining information displays the horizontal and vertical
distances to the hinge point and centerline from the current rod
location.
Note: All previous shots taken while locating a specific catch point
are shown in the map view as large
X ’s. These can be useful in
determining a situation where there is no catch point. (The slope
never intersects with the surface of the terrain.)
19. Once the catch point is satisfactorily located and staked, tap
6WRUH ! .
20. Enter a Point Name and Description in the corresponding fields
and tap 6WRUH &3 .
You can optionally stake a location at a specified horizontal offset
from the catch point (away from the centerline) by entering the
offset distance in the
Offset from CP field and tapping 6ROYH ! .
