I can't tell you how much I hate it when the dimension text on elevation dimensions moves by itself. As you can see in the attachment, the number decides to go back to its default position, which puts an enormous gap between the dimension and the marker. I don't know who came up with that distance, but it's [less than satisfactory]. I can drag those dimension values back day after day and they will wind up moving within a day or two.
My wish is to be able to control the gap between the dimension value and the elevation symbol. And if that's not possible, at least make the thing stay in place when I move it.
