Question

Quizplus · Accepted Answer

Positional tolerance at LMC (Least Material Condition) is the best choice to control the relationship of the feature surface and the true position at largest hole size. In LMC, the hole is at its smallest size, which means the feature is at its farthest position from the datum plane or axis. So, any variation from this position is controlled by the positional tolerance.
