What will be the permissible difference in the dimension of objects with the same value, e.g. 0.010 for Profile of a Line vs Profile of a Surface?
Jason first defines Profile of a Line and Profile of a Surface, explaining why Profile of a Line is a unique control and not often used. He walks through two examples to show that the design difference between Profile of a Line and Profile of a Surface depends on if and which datums are referenced in the feature control frame.
