POSITION

The PLTZF (Ø0.8) is located from specified datums (ABC) by basic dimensions. It specifies the larger positional tolerance for the location of the pattern of holes as a group.

The lower segment is referred to as the features-locating control. It governs the smaller positional tolerance (Ø0.25) for each feature within the pattern (feature-to-feature relationship). The FRTZF is free to locate and orient within the boundaries established and governed by the PLTZF. Datum A governs the orientation (perpendicularity) of the FRTZF.
