Convert FBX to 3DM

The Autodesk FBX (Filmbox) Interchange File format is a widely-used file format for 3D animation, geometry, and motion data. Initially developed by Kaydara and later acquired by Autodesk, FBX files facilitate efficient data transfer between various 3D software applications, supporting complex models, textures, and animation sequences. The format's extensibility and robust feature set have made it an industry standard in fields such as game development, film production, and virtual reality.

The 3DM file extension, standing for "3D Model", is associated with the openNURBS initiative, which facilitates the exchange of 3D geometry across CAD, CAM, CAE, and computer graphics software. Developed by Robert McNeel & Associates, it serves as the native format for Rhinoceros (Rhino) software. Introduced to address interoperability challenges, 3DM files store precise 3D models using NURBS (Non-Uniform Rational B-Splines) and polygon mesh representations. This format is widely adopted due to its open-source nature, enabling developers to read and write 3DM files without proprietary restrictions, thus promoting seamless data sharing in 3D modeling workflows.
