To Modify Tolerances of a Driven Dimension
Manipulation of the tolerances for a driven dimension is similar to that of the tolerances of regular dimensions. You can change the tolerance values and modify their format. A difference is that you can not set an upper or lower limit of the driven dimension, because the nominal value of the driven dimension is not changeable. The system calculates the limits based on the measurement between the two reference entities and the tolerance values.
