You can control distances or angles between 2D geometric objects or points on objects applying dimensional constraints and specifying values. You can also constrain geometry with variables and equations.
Dimensional constraints maintain specified distances and angles between geometric objects or points on objects.
You can display or hide dynamic and annotational constraints within a drawing.
You can control lengths, distances, and angles of objects by changing constraint values, by manipulating dimensional constraints using grips, or by changing user variables or expressions associated with dimensional constraints.
You can control geometry using mathematical expressions that include the names of dimensional constraints, user variables, and functions.
