At times you might want to modify a dimension to simply improve readability.
You can make sure that the extension or dimension lines do not obscure any
objects; you can reposition dimension text; and you can adjust the placement
of linear dimensions so they are evenly spaced.
The easiest way to modify dimensions individually is to use the
multi-functional dimension grips.
Modify Dimension Geometry
You can modify dimensions with the editing commands and with grip editing.
Grip editing is the quickest and easiest way to modify dimensions. How you
edit dimensions depends on whether the dimension is associative.
Modify Associative Dimensions
Associative dimensions retain their associativity to dimensioned objects
through many editing commands if both the dimension and the associated
geometry are selected and operated on with a single command. For example,
if a dimension and its associated geometry are moved, copied, or arrayed in
the same command, each dimension retains associativity with its respective
geometry.
In some circumstances, dimensions are automatically disassociated, including
■ If the associated geometric object is erased
■ If the associated geometric object undergoes a boolean operation such as
UNION or SUBTRACT
■ If grip editing is used to stretch a dimension parallel to its dimension line
■ If the association to a geometric object is specified using the Apparent
Intersection object snap, and the geometric object is moved so that the
apparent intersection no longer exists
In other circumstances, a dimension may become partially associated. For
example, if a linear dimension is associated with the endpoints of two
geometric objects and one of the objects is erased, the remaining association
is preserved. The disassociated end of the linear dimension may then be
associated with another geometric object using DIMREASSOCIATE.
NOTE The Command prompt displays a warning message if a dimension is
disassociated.
