3DM to GLTF Conversion
Step-by-step instructions to help you transform 3DM into GLTF with ease:
Download & Install Autoconverter
Convert 3DM files to GLTF format using Autoconverter - simply install and launch the software on your system.
Import 3DM File
Click Open... to open your 3DM file (.3dm) or drag and drop it into the application window.
Export to GLTF Format
Click Save As... to export your file to the GLTF file format (.gltf, .glb).

Rhinoceros 3D File
The native file format for Rhinoceros 3D (Rhino), a powerful and versatile NURBS-based 3D modeling software. As Rhino’s default format, 3DM is designed to store precise mathematical representations of curves, surfaces, and solids, making it ideal for high-accuracy modeling across industries.
Supported Geometry Types
Known for its precision and versatility, the 3DM format supports a comprehensive range of geometric data types, making it ideal for both organic freeform modeling and technical CAD applications, including:
- NURBS Surfaces: Enables mathematically precise, smooth, and editable surfaces essential for high-end industrial and automotive design.
- Polygonal Meshes: Stores tessellated geometry for 3D printing, rendering, and simulation.
- SubD (Subdivision Surfaces): Allows for flexible, organic modeling with editable subdivision geometry.
- Instance References: Lightweight object copies (not duplicates) that reference a single source, saving memory and ensuring synchronized updates.
3DM File Conversion
Our software solutions enable seamless conversion between 3DM and other major CAD formats (e.g., STEP, IGES, OBJ, DWG, STL). Autoconverter exports only polygonal meshes (STL, OBJ, etc.), suitable for 3D printing and real-time rendering, while Autoshaper preserves NURBS geometry, ensuring superior accuracy for CAD, CAM, and engineering workflows. Both converters can save 3DM files in legacy formats (Rhino 2.X - 7.X) or the latest Rhino 8.X version, ensuring smooth collaboration across different software environments.
Graphics Language Transmission File
A file format developed and maintained by the Khronos Group organization, a consortium of industry leaders that creates open standards for graphics, media, and parallel computing. It is designed to facilitate the efficient storage and exchange of 3D models.
Key Features of GLTF and GLB
- GLTF Versions: There are two versions of the GLTF file format that are available:
- GLTF 1.0: Supports basic geometry, simple materials with textures, basic skeletal animations with joint hierarchies, scenes with a single root node and a hierarchy of child nodes, etc.
- GLTF 2.0: Supports more features, such as PBR (Physically Based Rendering) materials, Draco compression, advanced skeletal animations, skinning, morph targets, etc.
- ASCII and Binary Modes: By default, a GLTF file is saved in ASCII text mode, which is human-readable and easy to edit. To save a GLTF file with all referenced texture images in binary mode, the GLB file extension should be used. This reduces the file size and the number of files.
- Embedded Textures: GLTF/GLB files allow for a more streamlined and efficient way to manage 3D assets. By storing textures directly within the file, these formats eliminate the need for separate image files, making the 3D model self-contained and easier to distribute.
GLTF/GLB File Conversion
Autoconverter and Automesher Application allow you to import and export GLTF and GLB files, and convert them into various other 3D file formats. Our products also support the use of Draco compression, which can significantly reduce the size of GLTF and GLB files without compromising visual fidelity.
