Composite Frame Position Tolerance

A Composite Frame Position tolerance is used for patterns of Features. It has two segments.

The Pattern Locating Tolerance Zone Framework (PLTZF)

The PLTZF constrains the variation of location of the Pattern with respect to external Datums.

The Feature Relating Tolerance Zone Framework (FRTZF)

The FRTZF constrains the Feature to Feature location variation within the Pattern.

The segment that is used to model the variation is chosen based on how the gap is described. The animations show the cases for PLTZF and FRTZF variation.
