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.
