COB to STL Conversion

Converting COB to STL has never been easier - just follow this quick guide:

  1. Install Autoconverter

    Download and install Autoconverter on your system. Launch the software to convert COB files to STL 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 STL Format

    Use Save As... to export your file to the STL mesh file format (.stl).

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.


STL What is an STL File? (STereoLithography Format Explained)

The STL file format (short for STereoLithography) was developed by 3D Systems, a pioneer in the 3D printing industry, to simplify rapid prototyping and manufacturing processes. Today, STL files are one of the most common file types used in computer-aided design (CAD), digital fabrication, and additive manufacturing workflows. STL models exclusively represent 3D geometry as a triangular mesh, offering high compatibility and fast processing across various 3D printers and modeling software.

Key Features of the STL Format

  • Lightweight and Simple: An STL file contains only the coordinates of vertices and normal vectors of triangles, making it extremely easy for 3D software and printers to interpret.
  • No Textures or Materials: STL models do not store color, texture, transparency, or material information, resulting in pure geometric representations without extra attributes.
  • Two Storage Methods: STL files are available in two distinct formats:
    • Binary STL: The most popular choice due to its small file size, ideal for faster saving, sharing, and printing.
    • ASCII STL: A human-readable text format that explicitly describes each triangle but produces significantly larger files.
  • No Fixed Units: The STL format does not define units (millimeters, inches, etc.). Most programs assume millimeters by default. Our STL files converter can automatically handle unit adjustments during file conversion if needed.

STL File Conversion Made Easy

Looking to convert STL files into other popular 3D formats? Autoconverter and Automesher Application offer powerful, high-precision STL file conversion to formats like STEP, OBJ, and SKP. These tools allow you to:
