Try using the Publish in Plant 3D project manager. right click on an opened Plant 3D model file in project manager. Choose publish on the fly out. The publish dialog will be invoked. Make sure to check the "3D DWF" box on the Model sheet. Once published the 3D object can be viewed in design viewer. There will be some data (tagging, description, etc.) will be seen in the Object Properties by choosing a Plant 3D object.
