3DM file format information

Extension	3DM
Full Name	Rhinoceros 3D
Type	3D Model
Mime Type	x-world/x-3dmf
Format	Binary

The 3DM file format is a 3D Computer Aided Design (CAD) format primarily used by the Rhinoceros CAD software. It enables the storage of both simple and complex 3D models within a standard package and has found many uses within the architectural, engineering, and manufacturing arenas.

The format allows the storage of 3D model geometric data, including mesh and texture coordinate data. This 3D data is stored in the NURBS format, allowing complex objects to be represented with high precision.

Although primarily designed for use with the Rhinoceros CAD software, 3DM files enjoy support amongst other CAD software, with many supporting the import and export of data to the format.

3DM Converter Capabilities

Currently, our 3DM converter can only convert from 3DM files, our developers are working to allow converting to 3DM files in future versions of our tools. Our 3DM 3D Model/Mesh tool does not support any color material data contained within 3DM files, so the converted file will not contain any color information.
