Engineering Graphics

EP-ED-8

Engineering Performance Matrix

Engineering Graphics are detailed and well-annotated visual illustrations that communicate the features and functions of a design or idea. Oftentimes, these representations are initially created by hand but they almost always transferred to a digital format using three-dimensional computer aided design software following a specific set of rules and guidelines. Sophistication in this process requires knowledge related to (a) the conventions for creating and reading engineering drawings, (b) dimensioning and tolerances, (c) two-dimensional sketching and computer aided design, and (d) three-dimensional parametric modeling. This core concept is important to the practice of Engineering Design as engineering professionals embody, communicate, and record their ideas through graphical representations that accurately detail and convey the features and performance expectations of their designs.
