identify source & mirror body

I have 2 bodies, I have to identify which is mirrored body & which is source. Any help appreciated.

Thanks

If you have a reference to the body, you can use the body object's .GetFeatures method to return the features used to construct the body. The mirror body would have a wavelink (mirror) or mirror geometry feature somewhere in the list. Finding a mirror feature in the list may be enough to confirm which is the mirror and which is the source. If not, you can query the mirror feature to find its parent features.
