Getting the Principal Axes of Inertia from Mass Properties

Hey everyone!

I've been trying to get the coordinates and orientation of a part in SolidWorks using the API, and I'm looking into using the mass properties for this purpose. I've found example code for accessing the centre of mass, and other data here: http://help.solidworks.com/2012/English/api/sldworksapi/get_mass_properties_of_activedoc_example_vb.htm . his has been very helpful, however, I also want to get the Principal Axes of Inertia, highlighted in the picture I've attached. Does anyone know how I can access that data?

Thanks!
