To stake a surface defined from two polylines relative to an alignment

1. Select Two strings in the Stake field and then tap each string in the map or tap to select each string from the list.

2. To stake points offset from the road, leaving the roadway clear for construction, define a construction offset.
3. Tap Start.

4. Use the plan or cross section view to navigate relative to the string. See Stakeout navigation.

   The reported deltas include the:

   • Station and Offset values for your current position relative to the alignment.

   • Go Left/Right value to each string.

   • V.Dist to the extension of the two strings.

   • V.Dist to the alignment.

   The diagram below shows the alignment (1), the two strings (2, 3), and the V.Dist to the extension of the two strings (4):

   

5. When the point is within tolerance, tap Measure to measure the point.

   When using a Trimble SX12 scanning total station in TRK mode with the laser pointer enabled, the Stakeout screen shows the Mark point softkey instead of the Measure softkey. Tap Mark point to put the instrument into STD mode. The laser pointer stops flashing and moves to position itself at the EDM location. When you tap Accept to store the point, the instrument automatically returns to TRK mode and the laser pointer resumes flashing. To remeasure and update the stakeout deltas, tap Measure after you tap Mark point and before you tap Accept. For more information, see EDM settings.

6. Tap Store.

   The software returns to the navigation screen.

   You can then:

   • Continue measuring points along the road.
   • Tap Esc to exit this stakeout method.
   • Change stakeout methods. To stake:
     • To the road, double-tap an empty part of the map.
     • To a string, tap the string in the map.
     • A Station on a string, tap the station on a string in the map.
