Distinguishing Mirrored Elements through the API

[Anonymous]

I'm having a problem with my program that I believe would be solved if I was able to distinguish if an object has been mirrored or not, and I’m not sure how to do that. 

I was able to find that when an object is mirrored it changes the “handedness” of the elements coordinate system, but I do not know if/how this could be accessed.

Any ideas?

A combination of these properties should sort you out for most family instances:

FacingFlipped

HandFlipped

Edit: Oh, I nearly forgot about the Mirrored property, that's probably handy also 🙂

Oh wow, i was not familiar with FamilyInstances.  That was a huge help, thank you for pointing me in the right direction!
