GD&T Matrix

This document compares geometric attributes in dimensioning and tolerancing to Y14.59-2009 tools. It contains a matrix that examines how size, form, orientation, and location geometric attributes control or do not control other attributes like size, form, orientation, and location both with and without datum references. It also examines modifiers like profile and runout.
