NOTE To simplify drawing organization and dimension scaling, it is recommended
that you create dimensions on layouts rather than in model space.
Parts of a Dimension
Here is a list of the parts of a dimension along with their descriptions.
Dimensions have several distinct elements: dimension text, dimension lines,
arrowheads, and extension lines.
Dimension text is a text string that usually indicates the measurement value.
The text can also include prefixes, suffixes, and tolerances.
A dimension line indicates the direction and extent of a dimension. For angular
dimensions, the dimension line is an arc.
