# To stake out the tunnel alignment

When staking an alignment defined in a TXL file, you can work from the map or from the menu.

To stake out the alignment:

1. In the map, tap the alignment and then tap Stakeout. Alternatively, tap and select Stakeout. Tap Alignments, select the alignment to stake and tap Next.

   If the alignment you want to stake out is not shown in the map, tap in the map toolbar to open the Layer manager and select the Map files tab. Select the file and then make the appropriate layer(s) visible and selectable. The file must be in the current project folder.

2. If you have not yet started a survey, the software prompts you through the steps to start the survey.

   The alignment is ready to stake, using your preferred stakeout method. For more information, refer to the topic for the selected method. See:
