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 (page 309) for more detail.
Define Variables and Equations
The -PARAMETERS command allows you to define custom user variables that
you can reference from within dimensional constraints and other user variables.
The expressions that you define can include a variety of predefined functions
and constants.
For more information about using variables and equations with constraints,
see
Constrain a Design with Formulas and Parameters (page 315)

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.
