Engineering Drawing and Graphical Communication Subject titles Intermediate

Engineering Drawing and Graphical Communication Subject titles: • Intermediate: Engineering Drawing and Graphical Communication • Advanced: Engineering Drawing

Intermediate level Engineering Drawing and Graphical Communication • There will be one exam paper 3 hrs duration. • SECTION A covers the core part of the syllabus. It carries 52% and four out of the five questions need to be answered. • SECTION B covers the Engineering Drawing part of the syllabus. It carries 24% and one out of the two questions needs to be answered. • SECTION C covers the Graphical Communication part of the syllabus. It carries 24% and one out of the two questions needs to be answered.

• All questions will be answered on A 2 size sheets, which will be provided. • Candidates are required to provide their own A 2 size drawing board and draughting equipment. • There is NO COURSE WORK (practical) at intermediate level. • This syllabus assumes knowledge of the SEC 29 Graphical Communication syllabus (Ordinary Level).

Subject Content Section A Most topics in Section A which are covered in the Ordinary Level Syllabus will be dealt with in more detail. Examples of new topics in Section A include: • Gears • Cams

Examples of new topics: Involute spur gears

Cams

Section B Engineering Drawing Part Assembled Components Detailed drawings

Engineering Drawing Part Isometric Projection First Auxiliary views

Section C Graphical Communication Part Perspective Design Process

Graphical Communication Part Charts Freehand

Advanced level Engineering Drawing

Advanced level Engineering Drawing • There will be two papers, Paper 1 and Paper 2 of 3 hrs duration each. • Paper 1 covers the core part of the syllabus. It carries 40% and five out of the six questions need to be answered. • Paper 2 covers the Engineering Drawing part of the syllabus. It carries 40%. Question 1 is compulsory. Another two questions out of three need to be answered. • CAD Portfolio (practical) carries the remaining 20%.

Most topics in Paper 1 are similar to those of Section A in the Intermediate Level but as with other new topics they will be covered in more detail. The compulsory question in Paper 2 will be an Orthographic Projection of assembled parts from separate parts of an engineering component. The following is an example of a Cam Operated Clamp.
