Most CAD software solutions are capable of producing triangle mesh 3D surfaces in LandXML format.

  • On-site: Trimble Business Center (TBC) survey CAD software
  • Design: Autodesk AutoCAD Civil 3D


  • Triangle meshes
  • Alignments (optional)


  • Design map 2D/3D (background map)
  • Pipes (usually as a DXF layer)

For the purposes of Infrakit, DXF files never have alignments.
