You add geometric tolerances in feature control frames. These frames contain
all the tolerance information for a single dimension. Geometric tolerances
can be created with or without leader lines, depending on whether you create
them with TOLERANCE or LEADER.
A feature control frame consists of two or more components. The first feature
control frame contains a symbol that represents the geometric characteristic
to which a tolerance is being applied, for example, location, profile, form,
orientation, or runout. Form tolerances control straightness, flatness, circularity
and cylindricity; profiles control line and surface. In the illustration, the
characteristic is position.
You can use most editing commands to change feature control frames, and
you can snap to them using the object snap modes. You can also edit them
with grips.
NOTE Unlike dimensions and leaders, geometric tolerances cannot be associated
with geometric objects.
You can also create annotative tolerances. For more information about creating
and working with an annotative tolerances, see
Create Annotative Dimensions
and Tolerances (page 309).
