TXL files

A tunnel file is a TXL file. TXL files typically contain a horizontal and vertical alignment along with templates that define the shape of the tunnel.

TXL files that you create by keying in the definition using Trimble Access Tunnels are automatically shown in the map once they are created.

If you are using a TXL file created in Trimble Business Center or that you have converted from a LandXML file, you may need to open the Layer manager and select the file to display it.

The tunnel file must be in the current project folder.

To display a TXL file in the map, tap in the map toolbar to open the Layer manager and select the Map files tab. Tap the TXL file once to make it visible (), and tap it again to make items in the file selectable ().

To change the labels shown in the map, for example to view alignment station values, tap and select Settings and then modify the options in the Display group box.

To rotate the alignment, tap and then tap the map and drag to rotate the view. The icon in the center of the map indicates the point of orbit.

From the map, you can select items in TXL files and then use them in other software functions, for example to perform cogo functions, such as a surface inspection. For more information, see Surface inspection.

You can convert a LandXML file that defines a tunnel to a Trimble TXL file for use in the Tunnels software.
