Think of a part that has a functional shape requirement related to one of the three orientation controls. In your post, describe the part, describe the orientation control that you think would be most important to it's function and why you think that it is important. What would happen if there was no control?

Finally, describe how you would apply an orientation control to the object. What would be the datum? What control would you use? What do you think an appropriate tolerance zone would be? How would you measure it to make sure that it was compliant?
