To add set out positions

Set out positions typically define bolt hole or drill hole locations within a tunnel. They are defined by the station range, offset values, and method. See Set out position requirements.

The station range can be defined as a single station or multiple stations with defined start and end stations:

Single station: Ideal for single bolt points, or pipes with a defined length that are designed for specific geological conditions.
Multiple stations: Ideal for blast holes that are repeated over multiple stations within a segment of the tunnel.

Trimble recommends that you define the tunnel template before you key in or import set out positions. If you define set out positions before defining the tunnel template they will be assigned to the first surface defined in the template when the tunnel is stored.

To key in set out position values

Tap Set out positions.
Tap Add.
Define the Station range using the Start station and End station fields.

If the set out position can be:
- Set out at any station, leave the Start station and End station fields empty.
- Set out from a specific station to the end of the tunnel, enter the Start station and then leave the End station field empty.
- Set out at only one specific station, enter the same station value in the Start station and End station fields.
- Set out at multiple stations within a range, enter the Start station and the End station.
A description of the defined station range is shown in the Station range group box, indicating where the defined set out position can be set out.
Select the Method to define the set out position and then fill out the fields for the selected method as required:

For each method, the Horizontal offset and Vertical offset values are relative to the alignment. If the alignment has been offset, the offsets are relative to the offset alignment. If the offset is to the left or down, enter a negative value or tap next to the offset field and select Left or Down.
- For a Blast hole set out position, in the Horizontal offset and Vertical offset fields enter the offset values that define the position to be set out.
- For a Radial set out position:
  1. Select the Surface that the set out position is relative to.
  2. In the Horizontal offset and Vertical offset fields, enter the offset values that define the position to be set out.
  3. To define a new center offset from the alignment, enter the Horizontal center and Vertical center values.
- For a Horizontal set out position:
  1. Select the Surface that the set out position is relative to.
  2. In the Vertical offset field, enter the offset value that defines the position to be set out.
  3. In the Direction field, select the direction that the horizontal offset is to be applied.
- For a Vertical set out position:
  1. Select the Surface that the set out position is relative to.
  2. In the Horizontal offset field, enter the offset value that defines the position to be set out.
  3. In the Direction field, select the direction that the vertical offset is to be applied.
- For a Multiple radial set out position:
  1. Select the Surface that the set out position is relative to.
  2. Enter the Interval between the radial positions.
- For a Pipe umbrella set out position:
  1. In the Horizontal offset and Vertical offset fields, enter the offset values from the alignment for the start point.
  2. In the End horizontal offset and End vertical offset fields, enter the offset values from the alignment for the end point.
  3. In the Length field, enter the length from the start station to the end station.
    
    The Length value is the 2D distance along the alignment, not the true 3D length.
If required, specify the Code.

The annotation entered in the Code field is assigned to the end of the position and is displayed when setting out the position.
Tap Store.
Continue adding set out positions as required.
When you are done, tap Close.
Tap Accept.
Enter the other tunnel components, or tap Store to store the tunnel definition.
