CAD Exchanger SDK
VRML Converter


VRML_Reader can read files and VRML_Writer can write files compliant with the format VRML97 (version 2.0).


  • polygonal representations
  • colors and materials
  • names
  • textures
  • assembly structure

Measurement Units

In accordance with the VRML format specification, 3D coordinates in VRML 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.
