The 3ds Max Data Exchange Interface (3DXI) is used for building exporters from 3ds Max. 3DXI is built on top of the existing 3ds Max SDK, providing wrapper interfaces for the most common aspects of data export from 3ds Max. 3DXI supports the following 3ds Max objects:

• Mesh

• Controllers - including Euler, constraints and Biped
• IK Chains
• Skin deformers
