How to Retrieve the Coordinates for the wall Openings

I would like to retrieve the coordinates (points) of a door which resides in a wall. I am getting the openings as below. Also, I am having the width. How can I find out the end point of the opening. Also, is there any easy other way to achieve this?

var openings = WallSelected.FindInserts(true, true, true, true);

Thanks in advance.
