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.
