Chapter 5 Tolerancing & Templates
Concentricity tolerance (circles, arcs)
Use concentricity tolerancing to compare the measured position of a feature to
the measured position of another concentric feature (reference feature). The
measured position of the of the basis feature is the nominal of the feature being
toleranced.
To perform a concentricity tolerance
Step 1
Highlight the desired feature in the features list.
NOTE
Use only a circle or arc. Concentricity tolerances do not apply to
other types of features.
Step 2
Click the concentricity button on the tolerance toolbar.
Step 3
Enter a value in the tolerance zone box as shown.
NOTE
The center point of the tolerance feature must lie within the
tolerance zone to pass. The tolerance zone is defined by the
diameter specified in the tolerance zone box. This is the tolerance
value.
CAUTION
Enter tolerance values in the appropriate units of measurement.
For example, if you are measuring in metric (mm) enter tolerance
data in metric (mm).
