Drawing a button under a 3D view will allow you to control the view when the button is pushed in a PDF.
You can also export out animation for all animated objects and cameras in the scene via the PDF Button Tag, which is automatically added to the Button Shape.
To export animation the object name MUST be unique. It only supports animating individual objects.
Animation also supports the 4D Publish Rigid Body Tag. Any physics animation does with this tag will also be exported. However they must also be individual objects. It will NOT work on compound objects or objects under a null for example.
