U3D 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.

OFF OFF File Format - 3D Object File for Polygon Meshes

The OFF (Object File Format) is a simple, ASCII-based 3D file format used for representing polygonal geometry in a lightweight, non-proprietary structure. Designed for academic and development use, the OFF format efficiently stores 3D model data using only vertices, faces, and optional edge information - ideal for geometry-focused workflows without material or texture metadata.

OFF File Features

  • Editable ASCII Structure: OFF files are plain text, easily viewable and editable in any standard text editor, making them perfect for manual modeling or debugging.
  • Supports Polygonal Geometry: Store 3D shapes using triangle meshes, quadrilaterals, or general polygons. Each face is defined by a list of vertex indices, allowing flexible model design.
  • Lightweight and Minimal: Unlike complex CAD formats, OFF excludes materials, textures, and metadata, focusing purely on geometric structure for fast, efficient modeling.

Convert OFF Files to Other 3D Formats

Our 3D conversion tools make working with OFF files fast and flexible. Autoconverter enables direct conversion of OFF mesh models to popular formats such as STL, OBJ, SKP (SketchUp), and PLY - preserving polygonal integrity throughout. For advanced workflows, Autoshaper can convert OFF files into NURBS-based formats like STEP, IGES, and BREP, ideal for CAD software and precision manufacturing.
