Some dimension characteristics are common to a drawing or to a style of
dimensioning and are therefore suited to be permanent dimension style
settings. Others generally apply on an individual basis and can be applied
more effectively as overrides. For example, a drawing usually uses a single type
of arrowhead, so it makes sense to define the arrowhead type as part of the
dimension style. Suppression of extension lines, however, usually applies in
individual cases only and is more suited to a dimension style override.
There are several ways to set up dimension style overrides. You can change
options in the dialog boxes or change system variable settings at the Command
prompt. You reverse the override by returning the changed settings to their
original values. The overrides apply to the dimension you are creating and all
subsequent dimensions created with that dimension style until you reverse
the override or make another dimension style current.
Example: Change a Dimension Style Override at the Command Prompt
You can override the current dimension style while creating a dimension by
entering the name of any dimensioning system variable at any prompt. In
this example, the dimension line color is changed. The change affects
subsequent dimensions you create until you reverse the override or make
another dimension style current.

Add Geometric Tolerances
You can add geometric tolerances that show acceptable deviations of form,
profile, orientation, location, and runout of a feature.
