Example of Dynamic 3d models

I am trying to figure out the correct syntax to add a dynamic 3d model to a widget. Is this possible. When I try to access widget.dataSources I get an error that widget.dataSources is not defined.

I am also interested in an example on how to dynamically moving a model using CZML. I know you all are busy but I bet we both would be very grateful for a some quick direction :slight_smile:
