I do not want the dimension to the side of the leader as you show it in your second picture. I want it center in the horizontal position, centered in the extension.. Just as I have shown it in my pic but the dimension is to be horizontal and centered.
I don't know a nice and easy/clean way of doing what you are after but if you had one normal dimension like you already have and set that to the side. Then Create a note and have the note link to that dimension by clicking on it. Then Hide the dimension. Then to create the dimension line I added a second dimension that is driven set the 'Custom Text Position' to the 3rd open, but then delete the <DIM> to remove the dimension number. I then positioned the note just below the line. Only issue is if you want to edit the original dimension you will need to show it first.
A bad solution but a solution none the less. Maybe someone else can find a better solution.
