He has provided instruction in geometric dimensioning and tolerancing and dimensional analysis to many industry, military, and educational institutions. He also has published one book, several articles, and given several academic presentations on those topics and dimensional management. Dr. McCuistion is an active member of several ASME/ANSI codes and standards subcommittees, including Y14 Main Committee, Y14.3 Multiview and Sectional View Drawings, Y14.5 Dimensioning and Tolerancing, Y14.11 Molded Part Drawings, Y14.35 Drawing Revisions, Y14.36 Surface Texture, and B89.3.6 Functional Gages.
The engineering drawing is one of the most important communication tools that a company can possess. Drawings are not only art, but also legal documents. Engineering drawings are regularly used to prove the negligence of one party or another in a court of law. Their creation and maintenance are expensive and time consuming. For these reasons, the effort made in fally understanding them cannot be taken for granted.
Engineering drawings require extensive thought and time to produce. Many companies are using three-dimensional (3-D) computer aided design databases to produce parts and are bypassing the traditional two-dimensional (2-D) drawings. In many ways, creating an engineering drawing is the same as a part production activity. The main difference between drawing production and part...
