Convert COB to 3MF - High Speed & Accurate 3D File Conversion

COB to 3MF Conversion

With our tools, changing COB to 3MF is a breeze - follow these simple 3 steps:

1. Install Autoconverter

   Download and install Autoconverter on your system. Launch the software to convert COB files to 3MF format.

2. Import COB File

   Click Open... to load your COB (.cob, .scn) file, or drag and drop it into the application window.

3. Export to 3MF Format

   Use Save As... to export your file to the 3MF mesh file format (.3mf).

COB 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.

3MF 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 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.
• Transparency and Opacity: Supports adjustable transparency for parts of the model, allowing the creation of translucent and transparent objects.
• 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.

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.
