With a little python you can use
n = 1 if it is a clevis
n = 1 and 2 for two rod's hangers
x = ElementHere.GetRodInfo() << This will substract all the Rod related information
x.GetRodEndPosition(n)" that will give you the points you need
I hope this makes sense, I use this to run trimble check scripts that will report if a hanger has been moved since the last update, but I think is what you looking for.
