Get dimension points

Hey everyone,

I am trying to place some text and although I have looked through all the properties and methods for a dimension in the help file I can't figure out how to get any points on a dimension apart from the reference points. Is there a way to get any of the 3 points in my picture? I need either the end points of the main dimenion line or a point on the text (the center would be ideal).

Thanks in advance for your help.
