CAD Exchanger SDK
FBX Converter


FBX_Writer can write files in FBX (7.2/7.4/7.5 version) at Binary and ASCII format.


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

Measurement Units

In accordance with the FBX format specification, 3D coordinates in FBX files are to be stored as default in centimeter. Therefore during export CAD Exchanger converts values in polygonal representation (stored in millimeters as explained here) multiplying them by 10.

FBX format do not support Base_LU_Micrometers and Base_LU_Mils length unit and at this case use Base_LU_Centimeters as default.
