Engineering, Graphics and Design

Engineering Graphics and Design (EGD) teaches internationally acknowledged principles that have both academic and technical applications. The emphasis in EGD is on teaching specific basic knowledge and various drawing techniques and skills so that the EGD learners will be able to interpret and produce drawings within the contexts of Mechanical Technology, Civil Technology and Electrical Technology.

The main topics of EGD:

• General drawing principles for all technological drawings

• Free-hand drawing

• Instrument drawing

• First- and third-angle orthographic projections

• Descriptive and solid geometry

• Mechanical working drawing

• Civil working drawing

• Isometric drawing

• Perspective drawing

• Electrical diagrams

• Interpenetrations and developments

• Loci of helixes, cams and mechanisms

• The Design Process

• CAD (Computer-Aided Drawing/Design)

The aims of EGD are to teach the following:

• Graphical drawings as the primary means of communication in the technological world

• Specific basic content and concepts within the contexts of Mechanical Technology, Civil Technology and Electrical Technology

• Various instrument and freehand drawing techniques and skills

• Solving technological problems through graphical drawings

• The application of the Design Process

• The implementation of CAD (Computer Aided Drawings/Design) as a drawing method
