The 3DM file format is an advanced 3D graphics format based around the NURBS method of representing 3D data. 3DM files are the native format used by the Rhinoceros 3D CAD application.
The advantages of using 3DM files to store 3D data are primarily down to the mathematically superior NURBS method compared to other 3D formats that store 3D objects as a series of triangles, which is how formats such as STL store 3D data.
3DM Converter Capabilities
As the 3DM format currently does not support the use of material colors when used by tool, your converted model will contain only the mesh geometry, material colors will not be transferred to your converted file.

The Khronos Group developed GLB files as a format for storing complex 3D models. The format was first introduced in 2015 and aimed to create a format that could be easily adopted by third-party developers. Subsequent versions have followed this initial release, adding more complex features.
Support for GLB files is growing and has found support in many modern 3D model editors, such as Blender, which currently supports importing from and exporting to the GLB format.
Mesh Geometry
At the heart of the GLB format is its ability to store 3D geometric mesh data, which comprises vertices, faces, normals (both face and vertex normals), and texture coordinates. The data is saved in a compact binary format, ensuring GLB files are compact and easy to distribute.
GLB Converter Capabilities
As the GLB format currently does not support the use of material colors in 3D models when created using our tool, your converted model will contain only the mesh geometry, material colors will not be transferred to your converted GLB file.
