Dimension associativity defines the relationship between geometric objects
and the dimensions that give their distance and angles. There are three types
of associativity between geometric objects and dimensions.
Associative dimensions. Automatically adjust their locations,
orientations, and measurement values when the geometric objects
associated with them are modified. Dimensions in a layout may be
associated to objects in model space. The DIMASSOC system variable is
set to 2.
Non-associative dimensions. Selected and modified with the geometry
they measure. Non-associative dimensions do not change when the
geometric objects they measure are modified. The dimension variable
DIMASSOC is set to 1.
Exploded dimensions. Contain a collection of separate objects rather
than a single dimension object. The DIMASSOC system variable is set to
0.
You can determine whether a dimension is associative or non-associative by
selecting the dimension and doing one of the following:
Use the Properties Inspector to display the properties of the dimension.
Use the LIST command to display the properties of the dimension.
A dimension is considered associative even if only one end of the dimension
is associated with a geometric object. The DIMREASSOCIATE command displays
the associative and non-associative elements of a dimension.
Special Situations and Limitations
You may need to use DIMREGEN to update associative dimensions after
panning or zooming, after opening a drawing that was modified with an earlier
release, or after opening a drawing with external references that have been
modified.
Although associative dimensions support most object types that you would
expect to dimension, they do not support the following:
Hatches
Multiline objects
2D solids
Objects with nonzero thickness
