Introductory Concepts

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.
