How do I lock the plan swing arc to the door leaf's solid geometry? I have created a door with a hollow metal frame for use in masonry walls, and I set up an offset parameter that will move the door and frame to different positions within the wall's thickness. The frame and open leaf symbolic lines move just fine when I change the offset parameter, but the swing arc doesn't move. I need to somehow attach or lock the arc's center point to the corner of the door leaf (either the solid geometry or the open leaf's symbolic lines, doesn't matter).

I should add that the single door w/ HM frame that I created works fine, but this double door family won't move the arc correctly as I described.
