Unique identifier of a body

Hi,

I'm working on a program that imports geometry from SolidWorks via API. The program enumerates bodies and just gets their triangulation data using ITessellation interface. I need to uniquely identify such data somehow. The first idea was to use IBody2.Name property and add such name to the path string which contains name of body's parent component and names of all of its parents (like a path to a subfolder on a disk). But unfortunately Name property is empty for all bodies I've seen. Is there any solution for this?

Thanks in advance.
