Stake Spiral Offsets
To stake a spiral curve with offsets in the horizontal and vertical directions.
- Define the spiral:
- Define the TS Point, the starting point of the spiral (tangent to the spiral point). Enter a point name manually, or select from the map
or from the list
of job points. Clicking the
button for GNSS survey opens the Topo dialog, or clicking the
button for optical survey opens the Sideshot dialog. There you can save the measured point to the current job and instantly enter this point to the corresponding field.
- In the Tangent Azimuth (or Tangent Bearing if bearing is selected to output directions) field, enter the direction of the tangent to the spiral at the TS point.
- Select between Radius / Chord Angle / Curve Angle to enter the radius parameter of the spiral as required.
- Select between Length / Spiral Constant to enter the length of the spiral at the ending point, or the constant of the spiral.
- In the Turn drop-down list, select the direction of spiral turn, either Left of Right.
- In the Dir drop-down list, select the direction of spiral moving:
- Select TS To SC, Tangent Spiral to Spiral Circle, this is the incoming spiral to the internal circle.
- Select SC To TS, Spiral Circle to Tangent Spiral, this is the outgoing spiral from the circle to the Tangent.
- In the Start field, enter the starting station to begin stakeout.
- Select the Include Transition Point check box to include start and end points if they do not fall on a designated station.
- The Stake Report field shows the name of the current stake report if it is set. Click
to open the Stake Reports List dialog to select the desired report or add a new one.
