These combined photos show a drafting technologist using CAD software.

CAD: Hemera/Thinkstock; computer: Hemera/Thinkstock

 

Drafting and design technologists use computer aided drafting (CAD) software to design technical drawings. These drawings may include orthographic views and three-dimensional representations. In this lesson you used some of the same techniques that a drafting technologist uses. Specifically, you created three-dimensional drawings from orthographic views.
