Importing LandXML Data

Supported version: LandXML version 1.2.

  • Alignment are supported at import and export.
    • Horizontal alignment:
      • Line-Line
      • Line-Curve-Line
      • Line-Spiral-Curve-Spiral-Line
      • Line-Curve-Curve-Line
      • Line-Spiral-Spiral-Line
      • Line-Spiral-Curve-Spiral-Curve-Line
      • Line-Spiral-Curve-Curve-Spiral-Line
      • Curve-Curve-Spiral-Line
      • Line-Spiral
      • Curve-Line
      • Line-Curve-Curve-Spiral-Line
      • Curve-Curve-Line
      • Line-Curve
      • Line-Curve-Curve
      • Curve-Spiral-Line
    • Vertical alignment:
      • PVI
      • CircCurve
      • ParaCurve(asymmetric and symmetric)
    • One horizontal alignment/ one or more vertical alignments
  • Vertical profile: ProfAlign

  • Superelevation data associated to alignement are supported at import and export.
  • Geolocation information is supported at import and export
    • If the information is missing in the imported LandXML file, you can choose a CRS available in 3DEXPERIENCE.
    • You can also overwrite the EPSG information found in the file by selecting another CRS.
    • If the EPSG information found in the file has no equivalent in 3DEXPERIENCE, import the EPSG before importing the LandXML file.
  • Surfaces are supported at import and export, and created in a dedicated geometrical set under the Terrain node
  • Geolocated points are supported at import and export, and created under a dedicated geometrical set under the alignment representation.

    Although geolocated points are points acquired through a topographic survey (Survey Points), they do not represent random points on a terrain, or a speed change position (Event Point), for example. They are reference points (coordinates: Lat/Long and UTM) for a specific project, normally used to:

    • Indicate the position for PIs
    • Limits of a parcel
    • Position of Light Pole
    • Vertical Signal
    • Representative Trees
    • Manhole position
    • Reference coordinates
    • Etc.
