# Plan and cross section view

During auto-scan, set out, machine positioning or when measuring a position in the tunnel, the plan view or cross section view of the tunnel appear alongside the map.

If available, the instrument video view is available instead of the map so that you can see where the instrument is pointing. In split screen view:

- To fine-tune the position of the instrument, use the Zoom level tool in the Video screen to zoom in and then press the up, down, left or right arrow keys on the controller keypad to move the instrument. The arrow keys do not move the instrument during scanning.

- When the map is shown, use the left or right arrow keys to increment points and the up or down arrow keys to increment stations.

- To switch to the map view, tap in the video toolbar. To switch to the video view, tap in the map toolbar.

- To view more softkeys, tap or swipe right to left (or left to right) along the row of softkeys.

- To make the map/video view or the plan/cross section view larger, tap and swipe across the screen.

Delta display

Information on the current position and, if applicable, its relationship to the selected set out position appears below the plan view or cross section view. For more information on available deltas, see Current position information.

To change the position of the delta display area, tap and swipe left. The plan or cross section view resizes to the closest preset position, so that the delta display area is positioned alongside the plan or cross section view, rather than below. Tap and swipe right to make the plan or cross section view smaller with the delta display area below.

Plan view

The plan view of the tunnel appears when you first select the tunnel.

Tunnel element | Indicated by
--- | ---
Horizontal alignment | Black line
Offset alignment (where applicable) | Green line
Current station | Red circle
Selected stations | Solid blue circle
Instrument position | Solid black circle
Direction instrument is pointing | Dashed red line

Stations shown grayed out have no vertical alignment or no template assigned and cannot be selected for scanning.

To select a station to measure:

- Tap the up or down arrow on the controller keypad (not available if the video view is shown alongside the plan view).
- Tap an individual station.
- Tap and hold on the screen and then tap Select a station. Select the station from the list in the Select a station screen.

The selected station appears as a red circle.

To deselect the point, tap elsewhere on the screen. Alternatively, tap and hold on the screen and then select Clear selection.

To add a station that is not defined by the station interval, tap and hold on the screen and then select Add station.

Tap and hold on a position on the alignment or offset alignment to view more information about the position.

To calculate grid and tunnel coordinates to confirm the definition before surveying the tunnel, tap Calc.

To pan around the screen, tap the Pan softkey and then press an arrow key.

To switch to the cross section view, tap .

Cross section view

To view a pop‑up window showing information including (where applicable), horizontal and vertical offsets, northing, easting, elevation, surface name, and code information for an item, tap any of the following:

Item | Shown as
--- | ---
Alignment | Red cross
Offset alignment | Smaller green cross
Pivot position | Circular green icon
Design points | Blue circles
Vertex point | Short green line
Blast hole set out point | A hollow black circle
Pipe set out point | A hollow black circle with a dot inside it
Any other set out point | A hollow black circle with a line defined by the origin of the position

Tap and hold on the alignment, offset alignment, design point, set out point, or vertex point to view its horizontal and vertical offsets, northing, easting, elevation, surface name, and code.

To view a station to scan from the cross section view, tap and hold on the screen and then select Scan current station.

To review other stations during scanning, tap the up/down arrows to view the next/previous station. The station being scanned is indicated in the top left of the screen. The station being viewed is indicated at the top center of the screen.

To switch to the plan view, tap .
