What is the best way to call out a slot? I have used basic dimension to reference the true center of the slot from 2 perpendicular datums. Then I called out the width of the slot and the height (the length from one tangent line off the full radius to the other tangent line) using standard dimension with tolerances. Then I called out the "2 X Full Radius" and also had a positioning block calling out diametric position of the center of the freature. Does this sound correct?
