What is GD&T? GD&T (Geometric Dimensioning & Tolerancing) is a symbolic language for researching, refining and ultimately encoding the functions of each feature of a machine part in order to specify permissible limits of imperfection to guarantee assembly and operation. Without GD&T, design processes cannot be function based, tolerance stack up analysis is impossible, manufacturing is a guessing game based on tribal understandings, and coordinate metrology is impossible. In spite of these reasonably well known, very positive forces, GD&T is not widely used, is rarely taught at universities and if used, is frequently misused. Why? Because the main resources for its use, the ASME and ISO GD&T standards, have become exceedingly complex and confusing in recent years. This includes 1) confusing terminology, 2) confusing symbols, 3) non-functional concept definitions, 4) a huge lack of rules and 5), a lack of application process guidelines. For the sake of industries around the world, it is therefore time to make GD&T much easier to use, and to use properly. But how? We will start with examples proving the need for repairs, then present examples of possible repairs, and finally, present ideas for encouraging and enabling their implementation.
