To stake out a line

Before you start, configure your navigation display settings. You can stake relative to a DTM or the design elevation, if required.

1. To select the line:

   • From the map, you can:
     • Select the line and tap Stakeout.
     • Select the two points that define the line, and then tap and hold in the map and select Stake out line.
     • Double‑tap the line in the map.

     When selecting a line to stake out from the map, tap near the end of the line that you want to designate as the start. Arrows are then drawn on the line to indicate the direction. If the direction is incorrect, tap the line to deselect it and then tap it at the correct end to reselect the line in the direction required. Alternatively tap and hold in the map and select Reverse line direction from the menu.

     If the line has been offset, the offset directions are not swapped when the line direction is reversed.

   • From the menu, tap and select Stakeout / Lines. Tap next to the Line name field and select:
     • List to view a list of previously defined lines to select from.
     • Two points to define the line from two points.
     • Azimuth to define the line by a start point and an azimuth.

2. In the Stake field, select the method and then fill out the required fields. Refer to the Line stakeout methods below.

   To select the station to stake, key it in, tap the Sta‑ and Sta+ softkeys, or tap next to the Station fields to select a station from the list. To select the start or end station, tap the Start station or End station softkey.

   To customize the stations available for stakeout, tap next to the Station field to view the Select station screen. See Stations available for stakeout.

   If the Station interval value is null, no station labels are displayed. If the station interval is 0, the station labels for the start and end stations plus any PI, PC or PT stations are displayed. If the station interval is a numeric value, labels for all stations are displayed (depending on the zoom scale).

3. To display the cut or fill relative to a surface during stakeout, enable the Cut/Fill to surface switch.

   1. In the Surface field, select the surface file from the current project folder. Only surface files that are set to visible or selectable in the Layer manager are listed.

      Alternatively, in the map select surfaces from BIM files. If you cannot select surfaces in the map, make sure the BIM file is set to selectable in the Layer manager. If the Selection mode button on the BIM toolbar is button is yellow , tap it and select Surface selection - Individual faces mode.

      You can select Surface selection - Whole object mode, but when using Whole object mode the software selects both the top and bottom surface and calculates the cut/fill to whichever surface you are closest to.

      The Surface field indicates the number of surfaces you have selected in the map.

      To select a different surface from the map, double-tap in the map to clear the current selection and then select the new surface.

   2. If required, in the Offset to surface field, specify an offset to the surface. Tap to select whether the offset is to be applied vertical or perpendicular to the surface. 

   3. To show the distance to the surface in the stakeout navigation screen, tap Options. In the Deltas group box, tap Edit and select the V. Dist surface at current position or the Perp. Dist to surface at current position delta. Tap Accept.

4. To review the line definition, tap Details.
5. Enter the Antenna height or Target height, the value of the station to be staked out (if any), and any further details, such as horizontal and vertical offsets.
6. Tap Start.

7. Navigate to the point.

   When the stake method is Station on line, Station/offset from line or Skew offset, you can edit the elevation. To edit do this, press the Space key or tap and enter the new elevation value. The original design elevation is automatically restored as soon as you change the design or the section of the design being staked, or once you exit stakeout. To restore the original elevation during stakeout after you have edited it, press the Space key or tap and then tap next to the Design elevation field and select Reload original elevation.

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

9. Tap Accept to store the point.
10. If you selected the View before storage option, the staked deltas you selected in the Stakeout options screen are shown. Tap Store.
11. The software returns to the navigation screen or, if you selected multiple items to stake out, the software returns to the Stake out items list.
