DYNCONSTRAINTMODE
Displays hidden dimensional constraints when constrained objects are
selected.
PARAMETERCOPYMODE
Controls how constraints and referenced user parameters are handled when
constrained objects are copied between drawings, Model space and layouts,
and block definitions.
PARAMETERSSTATUS
Indicates whether the Parameters Manager is displayed or hidden.
Apply Dimensional Constraints
Dimensional constraints maintain specified distances and angles between
geometric objects or points on objects.
For example, you can specify that the length of a line should always remain
at 6.00 units, that the vertical distance between two points be maintained at
1.00 unit, and that a circle should always remain at 1.00 unit in diameter.
When you apply a dimensional constraint to an object, a constraint variable is
automatically created for maintaining the constraint value. By default, these
are assigned names such as d1 or dia1, but you can rename them in the
Parameters Manager.
Dimensional constraints can be created in one of the following forms:
Dynamic constraints
Annotational constraints
The forms have different purposes. In addition, any dynamic or annotational
constraint can be converted to a reference parameter.
