There
are several dimension tools to display entity measurements and relations between
entities.
Elements of a Dimension
Dimensions usually consist of:
- A dimension line or arc
- Extension lines extending to the measured entity
- Dimension text
Ordinate Dimensions, Leaders, and geometric tolerances consist of:
- Dimension text
- Leader line
Dimensions are based on DimensionStyles. DimensionStyles are a named
set of defaults that use the requirements of specific industries or
applications.
Associative Dimensions
By default, Dimensions are related to entities. If you modify an
entity's geometry, the Dimensions automatically adjust their location, orientation,
and measurements to reflect the changes.
The Associative property on
the Properties palette shows whether a
dimension is associative or nonassociative.
As
the project evolves, changes may break the associativity between Dimensions and
their related entities. At any time, you can re-establish Dimensions' relation to
entities using the RelateDimensions command.
Use the Annotation Monitor
to identify dimensions that have broken their associativity with related
entities.
To use associative dimensions:
- Click or click (or type Options).
- In the Options dialog box,
click Drawing Settings
. You can enter
DrawingSettings.
- Expand Behavior and
select or clear Enable relative
dimensions.
