Export Tunnel Design Files (.txl)

Export tunnel design data contained in your project into a tunnel file (.txl) that can be opened in Trimble Access or another TBC project. The following tunnel design objects and their associated properties are included in the export as applicable:

Horizontal and vertical tunnel alignments
Tunnel corridor
Tunnel name
Tunnel templates
Tunnel template positions
Tunnel set outs, rotations, offsets

Note: You cannot export designed tunnel meshes and as-built data in a TXL file. Designed tunnel meshes can only be exported using the CAD DWG exporter.

To export a tunnel file (.txl):

Note: For general instructions on exporting data files, see Export Data.

Select Export in Home > Data Exchange.
The Export command pane displays.
Click the Corridor tab and select TXL Tunnel Exporter.
Complete the fields as shown in the following table. Then click Export.


Data
Horizontal/Vertical alignment	These read-only fields display the horizontal alignment and vertical alignment associated with the selected tunnel.
Tunnel	Select the tunnel design you want to export.
Begin/End station	Enter the station IDs that specify the horizontal beginning and ending points for the exported alignment. The stations must be within the range where the horizontal and vertical alignments overlap.
Station interval	Specify the frequency at which cross-sections can be viewed in Trimble Access. Note: As a tunnel design property in TBC, the Station Interval is used to determine the increments used with the video controls when you view a tunnel in the Tunnel Viewer.
File name
File name	Select or enter a name for the tunnel file and select the location for storing it.
Settings
File version	Select the version of TXL to which you want to export. Note: To include Arc Direction and/or Pipe Set Outs properties in an exported TXL file, be sure to use the latest version of the TXL exporter. The resulting TXL file cannot be imported into versions of TBC earlier than v5.80.
