When flatness is called out on drawing. How many hits and how far away are each hit has to be? What is the proper way to manually very a flatness call out?
So it looks like maybe a spring loaded ball, like a ballpoint pin, that the part rolls around on while moving up and down to show the flatness?? Is this correct???
