LEADER
Creates a line that connects annotation to a feature.
TOLERANCE
Creates geometric tolerances contained in a feature control frame.
Projected Tolerance Zones
Projected tolerances are used to make the tolerance more specific.
Projected tolerances are specified in addition to positional tolerances to make
the tolerance more specific. For example, projected tolerances control the
perpendicularity tolerance zone of an embedded part.
The symbol for projected tolerance ( ) is preceded by a height value, which
specifies the minimum projected tolerance zone. The projected tolerance zone
height and symbol appear in a frame below the feature control frame, as shown
in the following illustration.
