I sometimes scale down a drawing with details and dimensions (to be able to fit more details on a drawsing), then the dimension arrow heads scale down too. While in other drawings when I scale down the arrow heads remain the same size as before scaling down. So if I select some details that include dimension lines, and scale it down in half, the details are half the size, but the dimensions arrow heads are the same as bofore. What setting in dimensioning styles controls this aspect? Thanks.
