The learning objective is to identify the function of the part, how GD&T can be used to convey that functionality, and how to control and inspect for the geometric controls. Specify geometric tolerances, GD&T, that are applicable to the door hinge to ensure that it successfully achieves its two primary functions of connection and rotation movement. Assign datums as necessary. draw a sketch to show where the GD&T controls, and Datum(s) will be applied. Assign physical sizes and geometric tolerances.
