South Africa Grade 11 Engineering Graphics and Design Syllabus

This syllabus outlines the curriculum for Engineering Graphics and Design (EGD) at the Grade 11 level in South Africa. EGD emphasizes internationally recognized principles with both academic and technical applications. The focus is on imparting specific basic knowledge and diverse drawing techniques, enabling learners to interpret and create drawings within Mechanical, Civil, and Electrical Technology contexts.

Course Aims

EGD aims to develop learners' understanding of:

• Graphical drawings as the primary communication method in technology.
• Specific content and concepts within Mechanical, Civil, and Electrical Technology.
• Various instrument and freehand drawing techniques and skills.
• Problem-solving through graphical drawings.
• Application of the Design Process.
• Implementation of Computer-Aided Design (CAD).

Course Content

The Grade 11 syllabus expands upon the Grade 10 foundation, covering the following topics:

• Mechanical Drawing: Third-angle orthographic working drawings of simple assemblies, including fasteners (bolts, nuts, washers, keys), sections, conventional representations, and name/title blocks. [
• Civil Drawing: First-angle orthographic working drawings of single-story dwellings from foundation to ceiling, including annotations, dimensions, scales, abbreviations, fixtures (WC, bath, sink, shower, cupboards), hatching, colors, perimeters, floor areas, and name/title blocks.
• Isometric Drawing: Complex isometric drawings with auxiliary views and circles.
• Perspective Drawing: Two-point perspective drawings of simple castings, dwellings, and civil structures.
• Electrical Diagrams: Parallel and series circuit diagrams related to simple appliances and house wiring.
• Interpenetration: First-angle orthographic views of interpenetration curves between two in-line regular geometrical prisms and/or cylinders.
• Developments: Surface developments of interpenetrating solids, containers, hoppers, truncated pyramids and cones, and simple transition pieces.
• Loci (Helix): Principles of the helix in simple applications like augers, coil springs, and square screw threads.
• Loci (Cam): Principles of the cam in simple mechanical applications with uniform motion and wedge-shaped followers, including cam shaft and follower details, displacement graphs, and cam profiles.
• The Design Process: Application of the complete Design Process to a selected scenario, including problem identification, design brief formulation, research, idea generation, solution selection, presentation, and evaluation.
• CAD: Application and management of CAD software, creating presentation drawings for the PAT.

Assessment

Formal assessment comprises:

• Tests: Two tests covering theoretical concepts and problem-solving.
• Course Drawings: Thirteen drawings demonstrating practical skills and knowledge across various topics. [
• Mid-year Examination: Comprehensive assessment covering the first half of the syllabus.
• Practical Assessment Task (PAT): A design project implemented in three phases throughout the year, assessing the Design Process, drawing skills, CAD management, and drawing quality.
• Final Examination: Comprehensive assessment covering the entire syllabus.

The Practical Assessment Task (PAT) is a significant component, contributing 25% to the final mark. It involves applying the Design Process to a chosen scenario, producing presentation drawings using instruments and CAD, and compiling a portfolio.

The final mark breakdown is as follows:

• Continuous Assessment (Tests and Course Drawings): 25%
• PAT: 25%
• Final Examination: 50%

This syllabus provides a framework for the Grade 11 EGD course, equipping learners with essential graphical communication skills and knowledge for further studies and potential careers in various technological fields. [
