How to add metadatas to 3D dae files...?
The cad file used as an entry, the 2D files used as textures, environment, shaders...etc?
Yes sorry about the "Acrobat Tag" , the question was more for the CS6 suite, and the management of DAE files in Bridge and Photoshop Extended in a CQ5 DAM workspace.
But nevertheless, it should be cool if Acrobat X 3D could import directly Collada files...
There is no 'Acrobat X 3D'.
As of the Acrobat X Family, Adobe no longer imports non-native 3D file formats to PDF. All the translation of 3D models into the two permitted formats (PRC or U3D) is now the responsibilty of third-party vendors.
