The reason you won't see that happen is that a dimension does not have
constraints built into it. A dimension, just because it is horizontal, does
not have to remain horz if I change the geometry it's attached to. Place a
point or line (that is horz) at the point of tangency in question and then
it will lock down the sketch.

> yes agree quadrants and tangencies are different things. But it would be
nice to dimension horizontally or vertically in relationship to the sketch
on a tangency of a circle to a point.
