Stake Spiral and Offset – Screen Two
Station to Stake: is the desired station on the
spiral curve that you want to stake.
Station Interval: is the value that is added to
the Station to Stake after the Next Station
button is pressed.
Next Station : advances the Station to Stake by
the Station Interval.
Offset: is the horizontal distance of the offset
from the spiral curve. The offset occurs on the
left (while viewing the spiral from the Start
Point
) when the L is selected or on the right
when R is selected.
Note: An offset of zero would result in the spiral curve itself being
staked.
V. Offset : will result in the elevations for the design points to be
adjusted by the value entered here and will change the cut / fill
values accordingly. Design elevations will be lower when is selected,
and higher when U is selected.
Grade : specifies a slope from the spiral curve to the curve that is
being staked. When this is a non-zero value, the elevation for the
staked points will increasingly differ from the corresponding design
elevations on the spiral curve as the Offset value increases.
Height of rod: is the length of the rod.
Backsight… : opens the Backsight Setup screen (Page R-118).
< Back : returns to the previous screen.
Solve> : opens the third screen, described next.
