Early in the design stage the tolerance analyst sat with the designers to review the parts that were the basis of the camera design. It was here where major changes were made to modify the assembly features on the camera frame and mech plate. These changes reduced parts, and made more efficient use of exact constraint design. Moreover, these early changes were also instrumental in controlling variation in the mechanism assembly.

Several different tolerancing questions were asked of the tolerancing model. These questions were VERY specific to the actual function of the mechanism.
