Tolerances can be applied to profile measurements as bilateral or unilateral pass/fail boundaries. Bilateral
tolerances can be distributed equally or unequally around the nominal edges of the part, and are specified
by the user.
The X, Y and angular offsets, the maximum form error, the number of data points and tolerance pass/fail
results can be displayed in the Measure Profile window at the conclusion of the Fit operation. Upon
completion of the profile measurement the profile feature is added to the Features template.
