We start with the most commonly used
GD&T symbols, and then move on to
less frequently used controls.
-  How piece-part geometry is shown on    engineering drawings
-  Use of CAD-based data to define perfect    feature geometry
-  General rules controlling feature variability
-  How the allowable deviation from perfect    geometry is defined
-  How the piece-part is stabilized for    Manufacturing and Inspection
-  How GD&T is used to define allowable    deviations in Size, Form, Orientation, and    Location
-  Less frequently used geometric controls
-  Advanced concepts of GD&T
-  Impact of ISO GD&T Standards

         The WMES Approach
          to GD&T Education WMES instruction is based strictly on
the rules and definitions contained in the United States national standard for GD&T,
ASME Y14.5M-1994, "Dimensioning & Tolerancing".
