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.

3MF (3D Manufacturing Format) File
The 3MF (3D Manufacturing Format) is an open-source XML-based file format developed by the 3MF Consortium - an industry group composed of leading companies in the 3D printing sector. 3MF was specifically designed to address the limitations of older formats like STL, offering a richer, more extensible framework for modern additive manufacturing workflows. With 3MF, you can store not just the model geometry, but also color, textures, material properties, and metadata within a single compressed file.
Key Advantages of 3MF Over STL
Unlike traditional STL files that store only basic 3D geometry, the 3MF format provides a wide range of enhanced capabilities:
- Color Support: Enables full-color 3D printing by defining colors per triangle or per object, enhancing model realism.
- Texture Mapping: Associates 2D image textures with 3D surfaces, producing highly detailed and visually realistic prints.
- Embedded Metadata: Includes detailed information such as author, copyright, licensing, description, and more - improving project management and file documentation.
- ZIP Compression: Uses ZIP-based packaging to efficiently compress and bundle model data, reducing file size while maintaining structure and content.
3MF File Conversion and Workflow
Our Autoconverter and Automesher Application offer full support for importing, exporting, and converting 3MF files. Powered by the official lib3mf library, our software ensures high compatibility and reliable file processing across various 3D printing and CAD workflows.
Note: A current limitation of the 3MF format is its lack of support for nested group hierarchies. When converting complex 3D models with subgroup structures, the hierarchy will be flattened during export. Nevertheless, 3MF remains a highly advanced and preferred format for professional 3D printing, providing significant advantages over older standards like STL.
