Unfortunately, GDT has not become universally known as quickly as its originators had envisioned. GDT is a language, and like any language can be intimidating at first. Courses on GDT often quickly present the fundamentals, and then begin with highly complex, specialized applications without making sure that the fundamental tenets are understood. GDT must be presented at a level that ALL participants in the design, inspection, and manufacturing process are willing to understand. Without this common denominator, GDT will not be an effective communication tool.

Because of this, GDT specifications are often mis-interpereted or left out altogether. This is one unfortunate circumstance which this author attempts to rectify with the current narrative. As computer modelling of mechanical parts continues to increase the complex definition of engineering geometry, and as part tolerances become more and more precise, there is no doubt that GDT will fill the void for the description of 3D geometry for which it was designed. In the current marketplace, companies must produce products at the lowest practicable cost or suffer the consequences. GDT is the only existing way to define mechanical parts so that they fit and function with the widest, cheapest tolerances possible.
