1. Drawing is not to scale.
2. The tolerance of position that controls the location of the pattern of balls with respect to datums A and B.
For each ball there is a cylindrical tolerance zone eee perpendicular to datum C and located on true
position with respect to datums A and B as defined by e. The axis perpendicular to datum C of each ball
must lie within this tolerance zone
