(The course does not include engineering aspects of design but only the layout and drafting using CAD.) Students cannot receive credit for both CAD 140 and FME 140.
IV. Learning Objectives
The students will be taught the basic terminology of computer-aided design. They will learn how to operate the computers and plotters and how to select commands from the keyboard, tablet and screen menus. After learning the commands of the basic CAD system, they will use building systems software to learn the benefits of discipline specific programs.
