the drawing that I am talking about is for machining a body of butterfly valve, where diameter dimensions are following by the note GA. NO.
example (dia. 4.879 / 4.876 GA. NO.)
thanks again.

Usually used on a tapered surface, you would have a gage diameter and a gage height.
Measure the diameter at that height and it needs to meet the gage diameter values.
