COLLADA 3D Model (.DAE)
DAE (COLLADA - COLLAborative Design Activity) is an XML-based 3D interchange format managed by the Khronos Group, designed for exchanging digital assets between different 3D content creation tools. It supports geometry, materials, textures, animations, physics, kinematics, and complete scene hierarchies in a rich XML schema. COLLADA serves as a comprehensive interchange format for complex 3D scenes.
Advantages of COLLADA 3D Model
What the DAE format does well, and why you might choose it.
- Comprehensive support for geometry, materials, animation, physics, and scene hierarchy
- XML-based format that is human-readable and inspectable
- Supported by major 3D tools including Blender, Maya, 3ds Max, and SketchUp
Limitations of COLLADA 3D Model
What the DAEformat doesn't do well, and when to choose another format.
- XML verbosity leads to very large file sizes for complex scenes
- Implementations vary across software, causing compatibility issues
- Being largely superseded by glTF/GLB for real-time 3D interchange
What DAE files are used for
- 3D asset interchange between different modeling and animation tools
- Game engine asset import for Unity and earlier Unreal Engine versions
- Architectural visualization and CAD-to-3D conversion workflows

Frequently asked questions about DAE
What is a .DAE file?
DAE (COLLADA - COLLAborative Design Activity) is an XML-based 3D interchange format managed by the Khronos Group, designed for exchanging digital assets between different 3D content creation tools. It supports geometry, materials, textures, animations, physics, kinematics, and complete scene hierarchies in a rich XML schema. COLLADA serves as a comprehensive interchange format for complex 3D scenes.
What is the MIME type of DAE?
The official MIME type for DAE files is model/vnd.collada+xml. This is the value web servers and applications use to identify the format when transferring files.
What category does DAE belong to?
DAE is a 3D Model Converter format. Files in this category share common conversion paths and use cases.
How do I open a .DAE file?
DAE files are typically opened by software that natively supports the COLLADA 3D Modelformat. If you don't have a compatible application, the most reliable approach is to convert the file to a more universal format using the converters listed above. Most COLLADA 3D Model files convert to widely-supported alternatives in seconds.
