COB to 3DM - Convert COB Quickly and Accurately

COB to 3DM Conversion

Learn how to change COB to 3DM using our powerful converter in just a few steps:

1. Download & Install:

   Convert your COB files to 3DM format seamlessly using Autoconverter - simply install and launch the software on your system.

2. Import COB File:

   Either click Open... to browse for your .cob file, or drag and drop it anywhere in the application window.

3. Export to 3DM Format:

   Use Save As... to specify both location and filename (with .3dm extension) for your exported file.

Finding COB to 3DM conversion challenging? These trusted resources make COB files conversion simple:

• Embed Texture Images Directly into GLTF and GLB Files
• Convert Smooth Edges in SketchUp SKP Files
• Convert SketchUp SKP Models with Component Instances to STEP
• Convert 3D Mesh Files in the Batch Mode

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.

3DM Rhinoceros 3D File

The native file format for Rhinoceros 3D (Rhino), a powerful and versatile NURBS-based 3D modeling software. As Rhino’s default format, 3DM is designed to store precise mathematical representations of curves, surfaces, and solids, making it ideal for high-accuracy modeling across industries.

Supported Geometry Types

Known for its precision and versatility, the 3DM format supports a comprehensive range of geometric data types, making it ideal for both organic freeform modeling and technical CAD applications, including:

• NURBS Surfaces:

  Enables mathematically precise, smooth, and editable surfaces essential for high-end industrial and automotive design.

• Polygonal Meshes:

  Stores tessellated geometry for 3D printing, rendering, and simulation.

• SubD (Subdivision Surfaces):

  Allows for flexible, organic modeling with editable subdivision geometry.

• Instance References:

  Lightweight object copies (not duplicates) that reference a single source, saving memory and ensuring synchronized updates.

3DM File Conversion

Our software solutions enable seamless conversion between 3DM and other major CAD formats (e.g., STEP, IGES, OBJ, DWG, STL). Autoconverter exports only polygonal meshes (STL, OBJ, etc.), suitable for 3D printing and real-time rendering, while Autoshaper preserves NURBS geometry, ensuring superior accuracy for CAD, CAM, and engineering workflows. Both converters can save 3DM files in legacy formats (Rhino 2.X - 7.X) or the latest Rhino 8.X version, ensuring smooth collaboration across different software environments.
