Results of Exporting LandXML Files

When you export LandXML files, the points, alignments, and surfaces are handled in specific ways.

Points

When points are exported:

  • The point name or number is used in the "name" field.
  • Any valid feature codes are used in the "desc" fields.
  • For invalid feature codes, “*” is used.
  • The “LandXML.desc” attribute of the first “LandXML feature” is used for the “desc” attribute, and the “LandXML.code” attribute of the first “LandXML feature is used for the “code” attribute if they exist. Otherwise no “desc” or “code” attributes are written.
Alignments

When alignments are exported:

  • The data defining the alignment is written as an alignment in the LandXML file.
  • Both horizontal and vertical components are retained. Multiple vertical alignments can be exported with each horizontal.
Surfaces

When surfaces are exported:

  • Either the source data or the definition is used, but not both.
  • Points influencing the surface are saved as points.
  • 3D polylines, breaklines, and sloping lines influencing the surface are saved as breakline or contour point lists, depending whether they are pure 3D or 2D+elevation.
  • Internal breaklines are retained.
