The true position tolerance in GD&T informs us of the maximum allowable deviation of a feature (e.g. hole, slot) from its true position. By true position, we mean the ideal position of the feature according to design. The idea is that, for a feature, there is a true position that we desire. bak musicianhttp://ttc-cogorno.com/Newsletters/130810LocatingCoaxialFeaturesAtMMC.pdf ardas dipaWebThis part has two holes through the wall of a cylinder that must be centered on the axis of the cylinder and located 2.000 inches ± .005 from datum feature A.
