.dae File Extension
.dae file contains, which applications open it, and how Poly supports this 3D format. File extension details for .dae
Full Support| File type | COLLADA scene |
|---|---|
| MIME type | |
| Encoding | XML text |
| Operating systems | Windows, macOS, Linux |
| Opens with | Blender, Autodesk Maya |
| Poly support | Yes. Poly recognizes valid COLLADA scene files and makes supported geometry and scene metadata available. |
| Indexed by Poly | Yes. Poly indexes the filename and creates visual similarity information for supported 3D content; available metadata is shown in details. |
| Preview in Poly | Yes. Poly previews supported COLLADA scene geometry and scene content. |
| Poly agent | Yes. An optimized rendition of the 3D object or scene is provided to the agent, allowing compact yet information-rich multimodal interaction with 3D files. |
What kind of file is a .dae?
COLLADA is an XML interchange format for digital assets. A document can describe geometry, materials, effects, scene nodes, cameras, lights, and animation, with resources connected through XML references. The suffix normally uses the model/vnd.collada+xml MIME type.1
How do I open a .dae?
Blender and Autodesk Maya are established COLLADA authoring applications. Use either when you need to inspect or edit the scene, then export to GLB for compact interactive delivery, or 3MF when additive-manufacturing metadata is the priority.
Poly support for .dae
Poly previews supported geometry, makes the filename searchable, and provides visual similarity for supported 3D content. Available mesh and scene metadata appears in the details panel. An optimized rendition of the 3D object or scene is provided to the agent, allowing compact yet information-rich multimodal interaction with 3D files.
| Construct | Poly handling |
|---|---|
| Geometry | Meshes and geometric sources |
| Materials | Effects, materials, and image references when represented |
| Scene | Nodes, transforms, cameras, lights, and animation may be represented |
| Poly limitation | Preview fidelity depends on the constructs present |
Download the original when you need editing, simulation, print preparation, or exact project round-tripping.
History and alternatives
Khronos introduced COLLADA in 2006 as an open interchange specification for moving digital assets between authoring tools. Its broad schema supports more than a single mesh, but applications can interpret optional constructs differently. 1
Choose glTF or GLB for interactive scenes, OBJ for straightforward mesh exchange, and 3MF for manufacturing packages. Convert with a format-aware application and verify materials, scale, transforms, and resource paths afterward.
