point will be computed in areas that require a fill. Some people
prefer to compute this point somewhere other than the end of the
last segment to simplify the situation where a ditch meets an
area requiring a fill, which would otherwise result in an area with
two similar or identical negative slopes.
10. Use the and !! buttons to select the segment where you
want to compute the hinge point in situations requiring a fill for
each side of the road. (The hinge point will be computed at the
end of the segment listed here.)
11. Tap the 6WDNH &3 ! button to continue to the next
screen where the catch points at the current station
can be located. This screen is identical to the screens
used in the non-road layout slope staking routine. If
you are not familiar with these screens, refer to Page
146 below, and the Reference Manual.
12. Once the catch point is staked and stored, you will
return to the screen described above where the
station to stake can be advanced by the station
interval by tapping the
1H[W 6WD button and the
process can be repeated to stake the next catch
points.
