are assigned names such as d1 or dia1, but you can rename them with the

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.
Dynamic Constraints
By default, dimensional constraints are dynamic. They are ideal for normal
parametric drawing and design tasks.
Dynamic constraints have the following characteristics:
Maintain the same size when zooming in or out
Can easily be turned on or off globally in the drawing
Display using a fixed, predefined dimension style
Position the textual information automatically, and provide triangle grips
with which you can change the value of a dimensional constraint
Do not display when the drawing is plotted
If you need to control the dimension style of dynamic constraints, or if you
need to plot dimensional constraints, use the Properties Inspector to change
dynamic constraints to annotational constraints.
Annotational Constraints
Annotational constraints are useful when you want dimensional constraints
to have the following characteristics:
Change their size when zooming in or out
Display individually with layers
Display using the current dimension style
Provide grip capabilities that are similar to those on dimensions
Display when the drawing is plotted
NOTE To display the text used in annotational constraints in the same format as
used in dimensions, set the CONSTRAINTNAMEFORMAT system variable to 1.
