LEADER
Creates a line that connects annotation to a feature.
TOLERANCE
Creates geometric tolerances contained in a feature control frame.
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.
