FBX to STL Conversion: FAQ

What are FBX files?

The FBX vector format was initially associated with Filmbox and created as a version of the FLM format, offering more interoperability. Filmbox was a predecessor of Autodesk's MotionBuilder, created for motion capture devices by Canadian developer Kaydara, later acquired by Alias. Starting with 2006, FBX became a proprietary format of Autodesk. FBX is currently part of a set of tools known as Autodesk Gameware, used by designers in developing games and supporting character animation, AI and advanced user interfaces.

What are STL files?

STL is the proprietary format for a computer-aided design (CAD) program developed by 3D Systems.
