With parametric drawing, you can add constraints to geometry to ensure that the design conforms to specified requirements.
Geometric constraints determine the relationships between 2D geometric objects or points on objects relative to each other.
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.
You can control geometry using mathematical expressions that include the names of dimensional constraints, user variables, and functions.
