Door Swings

I am a new revit user and need some help with a door family. I am creating a door that I want to have a door angle opening option (i.e. 90 degrees or 45 degrees). I created a reference line and locked my solid form extrusion (door panel) to it and I also crated angle dimension and parameter. When I flex the parameter my solid extrusion piviots at the wrong location. How do I anchor (or move) the pivot point to the corner of my door frame? I have set up my HM frame to wrap around and adapt to the wall thinkness so I also need that pivot point to move with the corner of the door frame. Any help is appreciated.

You need to Lock the End of the Reference Line to the Jamb of the Door
You should be able to Tab thru the Selections until the End is Highlighted with a Square Box - then Lock/Align this to you Jamb/Reference Plane. DO this in Both the X & Y Planes.

That worked. Thank You!
