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. the origin of old englishWebbThe plastics in this norm are divided into tolerance rows.
