COB to IGES Conversion
Transform COB into IGES in minutes with our step-by-step instructions:
Install Autoconverter
Download and install Autoconverter on your system. Launch the software to convert COB files to IGES format.
Import COB File
Click Open... to load your COB file (.cob, .scn), or drag and drop it into the application window.
Export to IGES Format
Use Save As... to export your file to the IGES file format (.igs, .iges).

Caligari TrueSpace Object File
A proprietary 3D file type created by Caligari Corporation for their TrueSpace modeling and animation software. This format was designed to store complete 3D scenes including geometry, materials, and animation data from TrueSpace projects. While the software is no longer actively developed, COb files remain important for working with legacy 3D assets and converting older TrueSpace creations to modern formats.
Key Features of COB
- Complete 3D Scene Storage: COB files save entire 3D scenes including models, lights, and cameras in a single file.
- COB File Formats: There are two types of COB files:
- ASCII - Human-readable for manual edits and debugging in any text editor.
- Binary - Smaller file sizes and faster loading for complex 3D scenes.
- Material Support: The COB format stores color, texture, and basic material properties for 3D objects.
- NURBS and Mesh Data: Supports both NURBS surfaces and polygonal mesh geometry types.
COB File Conversion
Autoconverter and Automesher Application support importing COB files (TrueSpace format) and converting them to other 3D formats like STEP, SAT, FBX, SKP, and OBJ. The conversion preserves key elements including materials, textures, and UV coordinates from the original COB file. This is made possible through our use of the Open Asset Import Library, which ensures reliable cross-platform conversions. Note that only import is supported - you cannot export back to COB format.
Initial Graphics Exchange File
A file format widely used in the fields of CAD (Computer-Aided Design), CAM (Computer-Aided Manufacturing), and CAE (Computer-Aided Engineering), as it enables to transfer of 3D models and designs across different platforms and applications. Developed in the 1980s and standardized by ANSI and ISO, IGES remains a foundational yet legacy-neutral format for 3D data exchange.
Key Features of IGES/IGS
- Text-Based Geometry Storage: The IGES format stores all geometric data in human-readable text, enabling easy editing but potentially creating large files when exporting complex models with dense meshes.
- Color Representation: IGES maintains color information at the assembly level, preserving visual clarity in multi-component designs.
- Transparency Limitations: Unlike modern formats, IGES lacks alpha channel support, meaning transparency settings from original 3D designs won't carry through in exported files.
IGES/IGS File Conversion
Autoconverter provides full read/write capabilities for IGES files through the Open Cascade framework, ensuring compatibility with the latest specifications. The application works exclusively with triangulated mesh geometry when processing IGES files. For projects requiring native NURBS surface preservation, we recommend using Autoshaper, which maintains the original smooth surface definitions throughout conversion.
