How to Convert COB to OFF❓
Everything you need to convert COB to OFF in one place. Follow our step-by-step guide and achieve professional results with our trusted tool:
📥 Download and Install
Download and install Autoconverter on your system. This application will let you to convert your COB files to OFF format - no additional CAD software required.
📂 Open Your COB File
Go to File > Open… to load your COB file (*.cob, *.scn), or drag and drop it directly into the application window. The model loads into the 3D viewport for inspection before converting.
💾 Save As OFF Format
Go to File > Save As…, select OFF (*.off) as the output format, choose your destination folder and filename, then click Save to complete the COB to OFF conversion.
Caligari TrueSpace COB File Format
The COB file format was developed by Caligari Corporation for its 3D modeling and animation software, TrueSpace. COB files store complete 3D scene data including geometry, materials, textures, lights, and animation. Though TrueSpace is now discontinued, COB remains an essential format for preserving and converting legacy 3D content.
Key Features of COB Files
- Full 3D Scene Storage: COB files encapsulate entire scenes with objects, lighting, cameras, and animation data.
- Two Format Variants:
- ASCII COB: Human-readable format ideal for manual inspection and debugging.
- Binary COB: Compact format optimized for performance and faster loading times.
- Material & Texture Support: Includes surface colors, image textures, and basic shading information.
- Geometry Types: Supports both NURBS-based and polygon mesh 3D models for greater flexibility.
COB File Conversion Tools
Use Autoconverter and Automesher Application to import and convert COB files into modern 3D formats such as FBX, OBJ, SKP, STEP, and SAT. Our converters retain crucial data including UV mapping, materials, and mesh topology by utilizing the Open Asset Import Library (Assimp) for accurate and reliable file processing.
Note: COB files can only be imported - exporting to COB format is not supported.
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.
