The Import and Export commands on the File menu let you share 3D geometry with other 3D modeling programs.
3ds Max can import and export a variety of file formats, as described in this section.
Alembic is an interchange file format for computer graphics commonly used by visual effects and animation professionals as it distills complex animated scenes into a non-procedural, application-independent set of baked geometric results. It can handle animations with changing topology, making it useful for simulations such as fluids.
