[Tap Line…]: displays a map of all the polylines and alignments in the current job. Simply tap the line that you want
to offset stake and then tap
.
[To/From…]: opens a window where a range of points can be defined. The points within the specified range will
define the centerline of the road to be offset staked.
Begin Station: is the station assigned to the first point of the selected polyline or point range.
[Backsight…]: opens the
[Next>]: takes you to the second
Offset Staking - Screen 2
The second Offset Staking screen is used to define the cross section of the road that you want to offset stake.
1/2 Road Width: is the Left and Right width of the road, respectively, from the centerline to the edge of payment.
(See diagram below.)
X-Slope (%): is the Left and Right slope of the road, respectively, from the centerline to the edge of payment.
Note: A negative slope will result in water running from the centerline toward the edge of payment.
Stake Curb / Ditch: When checked, a curb or ditch and an offset can be defined beyond the edge of the pavement.
[Shape 1]:
/ […2]:
/ […3]:
: when staking a curb / ditch, this button allows you to select the shape of the
curb, ditch, or slope beyond the edge of pavement so cut / fill information can be computed on this surface if a random
offset is specified. The selected shape is displayed by an icon next to the button, as well as with a bold line in the
road’s cross-sectional profile at the bottom of the screen.
Note: The selected Shape is irrelevant if a random offset is not specified since the nodes are always in the same place
for each shape that uses the same Height and Offset values.
Height: is the height of the curb, ditch, or slope in feet or meters. A positive value is considered a curb and a negative
value a ditch.
Offset From Edge of Road: is the distance that the curb or ditch extends from the edge of pavement.
Note: The specified curb or ditch height and offset will be applied to both sides of the road.
Offset Staking - Screen 3
The third Offset Staking screen is used to select the station and section of the road to be staked and to specify an offset
distance from the design point.
