File format information for 3DM and OFF
Detailed information about the source and target file formats, including their capabilities and specifications.
3DM Format
3DM (Rhino 3D Model): A proprietary file format (.3dm) for Rhino software by Robert McNeel & Associates. It stores NURBS-based 3D models, ideal for precise design in architecture and engineering.
3DM Converter Capabilities
When converting 3D model or mesh files using our 3DM converter, we will attempt to convert color materials into a suitable format for use in the converted file.
OFF Format
OFF (Object File Format): A simple, open file format (.off) for 3D geometry, storing polygonal meshes with vertices and faces. It’s lightweight, mainly used in research and academic applications.

About the 3DM to OFF converter
FurniMesh's 3DM to OFF converter runs entirely in your browser using a WebAssembly glTF/3D-mesh pipeline — your file never leaves your tab, and the conversion completes in seconds for typical furniture-model files. Materials, UV maps, and scene hierarchy are preserved wherever the OFF format supports them. There's no sign-up (up to 20 conversions a day) and no watermark; files up to 50 MB — practical limits depend on your browser's available memory.
FurniMesh natively outputs four formats — GLB, OBJ, SKP (SketchUp 2017+), and BLEND (Blender 3.0+). Bridge conversion via this converter additionally produces FBX, STL, GLTF, 3DM (Rhino), PLY and OFF, and reads IFC, DAE, 3DS and 3MF files. Use the converter to bridge between supported formats — or skip the conversion step entirely if you don't have a source file yet (the FurniMesh library ships every model in all four native formats pre-rendered).
