Collada (COLLAborative Design Activity) is an XML-based 3D scene format managed by the Khronos Group. .dae stands for Digital Asset Exchange. Collada stores complete scene descriptions: mesh geometry, materials, textures, lights, cameras, animation curves, skeletal rigs, physics objects and kinematics. DAE remains in 3D printing (Cura), robotic simulation (ROS/Gazebo) and SketchUp workflows.
Ultimaker Cura accepts DAE files directly, making Collada useful for exporting colored multi-material models from Blender or Cinema 4D.
ROS URDF files reference DAE meshes for visual and collision geometry. Gazebo and RViz load robot models as Collada files.
SketchUp exports and imports DAE files for exchange with Google Earth, CityEngine and other geo-visualization tools.

Commonly converted to glTF/GLB (glTF is the modern replacement), to FBX for game engines, or to STL for 3D printing.
