ME104: Computer-Aided Design (CAD)

Unit 1: Engineering Graphics and Design   This first unit of the course will introduce you to the technical skill of drafting. We will cover the design process along with various design models. We will learn various methods of representing design like orthographic projections, pictorial sketches, and isometric projections. This unit will also cover other drawing representation techniques like section views, auxiliary views, and solid modeling. Finally, we will learn how to dimension and annotate the drawings with particular attention to the creation of working and assembly drawings.
