File with .FBX extension contains 2D/3D drawing or project blueprint saved as file in universal format that can be read by various programs. This proprietary format was designed by Kaydara in 1996 and later bought by Autodesk in 2006 for further development. Contains object model data along with information about transitions, video and audio files, and 2D/3D images.

FBX file preserves the full funcionality and fidelity of the original files. Software such as Cinema 4D, 3D Studio Max and PowerAnimator all support this file format. There exist tools dedicated to converting 3DS, DAE – COLLADA, DXF and OBJ into FBX format. Autodesk released SDK based on C++ programming language that supports two-way format conversion.
