2. SYNOPSIS
2
 Computer Aided Design provides knowledge and
exposure on the usage of CAD software.
 The course focuses on the application of the
software to produce drawing on graphics,
electrical/electronic component symbol, circuit
schematics and electrical wiring layout diagram.
 The skill acquired from this course will also
equip the students with the ability to learn and
use other similar software.

3. COURSE LEARNING OUTCOMES (CLO)

should be able to:
1. Describe computer aided design concept, applications
and capabilities in electrical engineering environment. (C2)
2. Use skillfully the draw and edit commands and the various
data input techniques in generating simple and complex
technical drawings. (C3)
3. Draw and produce with precision the symbol graphics,
electronic circuits schematics and electrical wiring layout
diagrams faster and neat. (P3)
