You can display or hide dynamic and annotational constraints within a drawing.
Display or Hide Dynamic Constraints
DYNCONSTRAINTDISPLAY system variable.
You can hide all dynamic constraints globally within a drawing to reduce clutter when you want to work with geometric constraints only, or when you need to continue other work in the drawing. You can turn on their display when needed from the ribbon or with theBy default, if you select an object associated with a hidden dynamic constraint, all dynamic constraints associated with that object will display.
Display or Hide Annotational Constraints
You control the display of annotational constraints as you would with dimension objects—you assign them to a layer and turn the layer on or off as needed. You can also specify object properties for annotational constraints such as dimension style, color, and lineweight.
