Notes on using the LandXML to TunnelXML file style sheet
======================================================

The LandXML to TunnelXML file style sheet is designed to be used only with the 
ASCII File Generator program.  

The style sheet will let you convert a LandXML file containing horizontal 
alignment, vertical profile and tunnel profile data (recorded as CrossSectSurf
elements) to a TunnelXML containing the same design data.

If you do not already have the ASCII File Generator program installed on 
your computer, you can install it from the following URL:
http://www.trimble.com/tsc_ts.asp?Nav=Collection-59283
After installation the ASCII File Generator program is available from the 
Start|Programs|Trimble Office|Utilities menu group.

The ASCII File Generator installation will place a number of style sheet files 
in the \Trimble Survey Controller\Custom ASCII Files folder and you can add the 
downloaded 'SierraSoft LandXML To TunnelXML.xsl' file to the folder.

Carry out the following steps to extract the tunnel definition from a LandXML file 
and write it out to a TunnelXML file:

1. Start the ASCII File Generator program and select the appropriate LandXML 
   file using the Browse... button associated with the 'Source JobXML or Job 
   file' field.  In the Open File dialog presented select 'XML files' from the 
   drop down list in the 'Files of type' field to assist in locating the LandXML 
   file. 

2. Select 'SierraSoft LandXML To TunnelXML' in the 'Output format' field.

3. Click OK to start the conversion operation.

4. If there is more than 1 alignment defined in the LandXML file, a pop-up 
   dialog will be presented asking you to select the alignment to be exported. 
   Choose the alignment you want exported to the TunnelXML file from the drop 
   down list of available alignments.

5. If there is more than 1 tunnel CrossSectSurf defined in the LandXML file 
   for the selected alignment, a pop-up dialog will be presented asking you to 
   select the profile to be exported.  Choose the profile you  
   want exported to the TunnelXML file from the drop down list of available 
   profiles.


After these steps the TunnelXML file will be written and you are provided with a 
File Save dialog to let you choose where the file should be saved.
