When I add a tolerance to a dimension on an older drawing, I often find that the font size of the tolerance is the same as the dimension when I would like it to be half the size. I go to change the size in the document properties but the tolerance I have already written won't change. I have to delete dimension altogether and add a new one for the tolerance font change to take effect. This is fine but I'd like to know if there's a way I can avoid rewriting my dimensions each time I edit an older drawing. I tried hitting rebuild but that doesn't work.

Any ideas?
