If you change the value of a dimensional constraint, all the constraints on the
object are evaluated, and the objects that are affected are updated
automatically.
Also, constraints can be added directly to segments within a polyline as if they
were separate objects.
NOTE The number of decimal places displayed in dimensional constraints is
controlled by the LUPREC and AUPREC system variables.
Compare Dimensional Constraints with Dimension Objects
Dimensional constraints are different from dimension objects in the following
ways:
Dimensional constraints are used in the design phase of a drawing, but
dimensions are typically created in the documentation phase
Dimensional constraints drive the size or angle of objects, but dimensions
are driven by objects
By default, dimensional constraints are not objects, display with only a
single dimension style, maintain the same size during zoom operations,
and are not outputted to a device
If you need to output a drawing with dimensional constraints or use dimension
styles, you can change the form of a dimensional constraint from dynamic
to annotational. See
Apply Dimensional Constraints on page 892 for more
detail.
