SYNOPSIS

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.
