Can some one explain the root point of planar surface to me? I have a macro that tries to find faces coincident to a pre-selected face while in an assembly, and while my testing for planar surfaces that are parallel works, I would like to further limit the faces to ones that are co-planar to within some tolerance. I apply the  transform to the root point of one of the planar faces, and it ends up catching faces that are not coincident within the tolerance. I was reading through the Transform2 help page and noticed that this creates the transform relative to the root component, does that mean that mean if the pre-selected face is not the root component then it neeeds to be transformed as well?

Any insight on this process or potential workarounds would be greatly appreciated.
