Universal 3D Model Exchange - U3D File Format
The Universal 3D (U3D) format is an open, royalty-free 3D file standard designed for efficient sharing of 3D models across different platforms and applications. Originally developed by the 3D Industry Forum and now standardized by ECMA International (ECMA-363), U3D files offer compressed storage of 3D triangular meshes, along with attributes like color, transparency, and texture mapping. U3D is widely known for enabling interactive 3D graphics directly within PDF documents.
Main Features of U3D Files
- Open and Royalty-Free: Maintained as an international standard, ensuring no licensing fees for developers and users.
- 3D PDF Support: Integrates seamlessly with PDF files (ISO 32000 standard), allowing users to embed, view, and interact with 3D models inside Adobe Acrobat Reader and other compatible viewers.
- Efficient Compression: Stores 3D geometry and properties in a compact, binary format optimized for fast transmission and document embedding.
- Cross-Platform Compatibility: Enables 3D model viewing across Windows, macOS, and Linux without requiring proprietary software.

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.
