WebCylindricity essentially controls the outside "shape" and "form" of the part similarly to how Rule 1 does, except that it is used to FURTHER REFINE that tolerance. Say, for example, you had a pin with a rather large tolerance on its diameter. You might be willing to accept the pin at any size, but you need it to be relatively straight and round. shutter island film analysis
