Stake Curve and Offset
[Stakeout] [Curve and offset]
The Stake Curve and Offset screen is used to stake stations on a curve or at an offset to it at fixed station intervals.
PC Point: is the starting point of the curve (point of curvature).
[PC Tangent Azm] / [PC Tangent Brg]: defines the azimuth or bearing, respectively, of the tangent at the PC Point.
[Radius] / [Degree Arc] / [Degree Chord]: defines the radius, degree, arc, or degree chord of the curve, respectively.
Turn: defines if the curve turns to the Left or Right from the point of view of the PC.
Begin Station: is the station assigned to the PC Point.
[Backsight…]: opens the
[Next>]: takes you to the second
screen, described below.

Curve and Offset – Screen 2
Station to Stake: is the desired station on the curve that you want to stake.
Station Interval: is the value that is added to the Station to Stake after the [Next Sta] button is pressed.
[Next Sta]: advances the Station to Stake by the Station Interval.
Offset: is the horizontal distance of the offset from the specified curve. The offset occurs on the left (while viewing the
curve from the PC) when the L is selected or on the right when the R is selected.
Note: An offset of zero would result in the specified curve 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 D is selected, and higher when U is selected.
[Grade]: specifies a slope from the specified 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 specified curve
as the Offset value increases.
Height of Rod: is the length of the rod.
