Tolerancing
Applying tolerances to features
Tolerances are applied to feature measurements using tolerance screens. The method of applying toler-
ances to features is diagrammed below and is nearly identical for all tolerance types. In the following
example, a true position tolerance is applied to a circle feature.
Select a feature from the feature list
Touch the desired feature in the feature list to select it. In this example
a circle is selected.
Select the desired fit algorithm
Touch the Fit choice field to display a menu of available fit algorithms, then touch the desired fit algorithm
button. In this example, the fit algorithm is changed from Best Fit to Least Radial.
Display the TOL screen
Touch the Tol screen button to
display the tolerance screen.
