To export to LandXML, you need to load a LandXML file that already contains a centerline covering all or part of the
station range in the SCT cross section file. Otherwise, you will see an error message.
Despite the message, you can add the horizontal alignment portion to the LandXML file after creating the file with
sections only. However, if you first create a LandXML file containing one or more alignments, then choose that existing
LandXML file to export to, you can select among those centerline alignments when making the cross section file.
Section files in FAST Survey can contain descriptions useful for reference in other routines such as Stake Road. If
descriptions are found in the source section file, they will be captured by the import process into the “.sct” file for use in
FAST Survey.
Pipes running longitudinally along horizontal alignments can be imported in the form of cross sections using the
Columnar Text form. The example below shows the layout of the pipe format that is recognized by FAST Survey.
