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

The LandXML to TunnelXML file style sheets are designed to be used only with the 
File and Report Generator program (or the earlier ASCII File Generator program).  
There are 2 style sheets available in the in the zip file:

  The 'LandXML to TunnelXML (single surface).xsl' style sheet will create
  TunnelXML files suitable for use with Trimble Access versions prior to 
  version 2013.10 where only one profile surface could be handled.  The style
  sheet will allow you to select the profile surface to be used if the LandXML
  file has more than one profile surface defined.

  The 'LandXML to TunnelXML.xsl' style sheet will create TunnelXML files 
  suitable for use with Trimble Access version 2013.10 and later that can work
  with more than one profile surface.

The style sheets will let you convert a LandXML file containing horizontal 
alignment, vertical profile and tunnel profile data to a TunnelXML containing 
the same design data.  Note that as the tunnel design data in a LandXML file 
can be recorded in the file in a wide variety of forms, the style sheet may 
not be able to successfully interpret the data in the LandXML file.

If you do not already have the File and Report Generator program installed on 
your computer, you can install it from the following URL:
https://forms.trimble.com/globalTRLTAB.asp?nav=Collection-59798
Both style sheets are designed to work with version 2.0.1 of the File and Report 
Generator (or version 1.0.23 of the earlier ASCII File Generator).

After installation, the File and Report Generator program is available from the 
Start|Programs menu group.

The File and Report Generator installation will place a number of style sheet files 
in the \Report Style Sheets folder and you can add the downloaded 'LandXML To 
TunnelXML.xsl' and 'LandXML to TunnelXML (single surface).xsl' files 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 File and Report 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 'LandXML To TunnelXML' (or 'LandXML to TunnelXML (single surface)') 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 using the 'LandXML to TunnelXML (single surface).xsl' style sheet and if
   there is more than 1 tunnel profile 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.
