About Composite Tolerances

A composite tolerance specifies two tolerances for the same geometric characteristic
of a feature or for features that have different datum requirements. One tolerance
relates to a pattern of features and the other tolerance to each feature within the
pattern. The individual feature tolerance is more restrictive than the pattern tolerance.

In the following illustration, the point where datums A and B intersect is called
the datum axis, the point from which the position of the pattern is calculated.

A composite tolerance could specify both the diameter of the pattern of holes and
the diameter of each individual hole, as in the following illustration.

When you add composite tolerances to a drawing, you specify the first line of a feature
control frame and then choose the same geometric characteristic symbol for the second
line of the feature control frame. The geometric symbol compartment is extended over
both lines. You can then create a second line of tolerance symbols.
