CAD Exchanger SDK
X3D Converter


X3D_Writer can write files in X3D format (ISO/IEC 19775).


  • polygonal representations
  • colors and materials
  • meta-data (names)
  • assembly structure

X3D Measurement Units

In accordance with the X3D format specification, 3D coordinates in X3D files are to be stored in meters. Therefore during export CAD Exchanger converts values in polygonal representation (stored in millimeters as explained here) multiplying them by 1000.
