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 palette 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.
After plotting, you can use the Properties palette to convert annotational
constraints back to dynamic constraints.
Reference Parameters
A reference parameter is a driven dimensional constraint, either dynamic or
annotational. This means that it does not control the associated geometry,
but rather reports a measurement similar to a dimension object.
