Conversion from 3DEXPERIENCE to Collada is not supported yet :(

3DEXPERIENCE is a collaborative platform for creating products and services in the cloud, particularly in the area of design, engineering, and manufacturing.

3DEXPERIENCE allows everyone involved to interact and work together on a product: exchange data, contribute to a design, build and test a virtual model. \n\nThe platform also has its marketplace for on-demand manufacturing, 3D parts catalog, and engineering services.

Collada (COLLAborative Design Activity) is an interchange format for interactive 3D applications. Originally developed by Sony Computer Industry, now it is managed by the Khronos Group, a member-funded industry consortium, which now shares the copyright with Sony, Recently Collada has been well adopted by ISO as a publicly available specification, ISO/PAS 17506.

It is an XML-based schema that allows data exchange among 3D Digital Content Creation tools, such as SketchUp, Maya, 3ds Max, and Rhino. COLLADA files have the *.dae file extension, which stands for digital asset exchange.
