3DM to OFF Conversion
Converting 3DM to OFF is simple - just follow our straightforward guide:
Install Autoconverter
Download and install Autoconverter on your system. Launch the software to convert 3DM files to OFF format.
Import 3DM File
Click Open... to load your 3DM (.3dm) file, or drag and drop it into the application window.
Export to OFF Format
Use Save As... to export your file to the OFF mesh file format (.off).

Rhinoceros 3D (3DM) File Format
The 3DM file format is the native format for Rhinoceros 3D (Rhino), a leading NURBS-based 3D modeling software used across industries like architecture, engineering, and industrial design. 3DM files accurately store mathematical representations of curves, surfaces, solids, and meshes, making them essential for precision 3D modeling and CAD workflows.
Key Features of 3DM Files
- NURBS Geometry: Supports precise, smooth surfaces critical for advanced design and engineering projects.
- Polygonal Meshes: Stores tessellated 3D models ideal for rendering, simulation, and 3D printing workflows.
- SubD Surfaces: Allows flexible, editable subdivision modeling for organic shapes and complex surfaces.
- Instance References: Saves memory by creating linked object instances, optimizing large and detailed models.
Convert 3DM Files Seamlessly
Autoconverter and Autoshaper simplify 3DM file conversion to popular formats like STEP, IGES, OBJ, STL, and DWG. Automate the export of 3DM polygon meshes for 3D printing, or preserve NURBS data for engineering-grade CAD models. Save files in legacy (Rhino 2.X–7.X) or latest Rhino 8.X formats to ensure compatibility across all project environments.
Object File Format
A straightforward, human-readable file format designed for representing 3D polygonal models. As a lightweight alternative to complex CAD formats, OFF focuses on storing essential geometric data - vertices, edges, and faces - without proprietary constraints.
Key Features of OFF
- ASCII Text Files: OFF files are text-based and use a simple syntax to store geometric data of 3D objects. The files can be easily edited and viewed with any text editor or viewer.
- Polygonal Shapes: The OFF format allows to store 3D triangles, quads, and other generic polygonal shapes. Each shape is defined by a list of vertices and a list of faces.
- Limitations: OFF files support only geometric data - materials, textures, and group names from source files are discarded during conversion.
OFF File Conversion
Our software offers two specialized approaches for OFF file conversion. Autoconverter handles conversion of OFF files to common mesh formats including STL, SKP, OBJ, and PLY, maintaining the original polygonal structure. Autoshaper provides advanced conversion of OFF polygonal data into smooth NURBS surfaces, exporting to BREP, STEP, and IGES formats for CAD workflows.
