The minimum entrance requirement for this subject is 45% in Maths examinations (Maths CASS is excluded).

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 EGD learners will be able to interpret and produce drawings within the contexts of Mechanical Technology, Civil Technology and Electrical Technology.

The main topics covered in EGD are: 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).

Each EGD learner must have the approved EGD textbook with self-explanatory examples and exercises for each topic. A workbook/work file may be used only in conjunction with a textbook and not as a substitution for a textbook.

The following requirements should be the responsibility of the learner: a large file, masking tape, drawing pencil: 2H, 3H or 4H, eraser, ruler, 30°/60° drawing set square, 45° drawing set square, drawing compass, preferably with an adjustment wheel, divider, small protractor, dust cloth, calculator.

EGD requires the ability to apply knowledge. It is not a learning subject, rather one that requires regular practice. There is a strong correlation between a learner’s performance in Maths and EGD, hence the minimum entrance requirement.
