This week marks a critical juncture in your Grade 12 Engineering Graphics and Design (EGD) journey. We're focusing specifically on portfolio and Practical Assessment Task (PAT) completion, recognising that these elements collectively represent a significant portion of your final mark and, more importantly, demonstrate your accumulated understanding and practical application of EGD principles.
The Importance of Portfolio and PAT Completion Your portfolio and PAT represent the culmination of your EGD knowledge and skills. The PAT is a substantial practical project designed to assess your ability to apply EGD principles to a real-world design challenge. The portfolio serves as a documented collection of your work throughout the year, demonstrating your growth, understanding, and proficiency in EGD. Both elements are vital for demonstrating your competence and readiness for further studies or careers in related fields. Components of the Portfolio (Refer to CAPS document for exact requirements – this is a general example)
Working Drawings: A complete set of orthographic projections, including plan, elevation, and sections, of your PAT project. These must conform to SANS standards.
Isometric or Perspective Drawings: A visually appealing representation of your PAT project to communicate the overall design.
Freehand Sketches: Demonstrate your ability to quickly visualize and communicate design ideas through sketches.
CAD Drawings: If applicable, include CAD drawings created using software such as AutoCAD, demonstrating your digital drawing skills.
Research and Development: Evidence of your research, problem-solving process, and design development stages. This could include sketches, notes, and design iterations.
Reflection and Self-Assessment: A written reflection on your learning journey, challenges faced, and lessons learned throughout the year. PAT Requirements (This will vary depending on the specific PAT set by the IEB/DBE) The specific PAT requirements will vary each year, but generally include: Design Brief: A clear and concise statement of the design problem you are tasked with solving.
Design Process: A documented account of your design process, including research, brainstorming, concept development, and refinement.
Working Drawings: Accurate and detailed working drawings of your final design, conforming to SANS standards.
Assembly Drawings: If your design involves multiple parts, assembly drawings showing how the parts fit together.
Bill of Materials: A list of all materials required to construct your design, including quantities and specifications.
Calculations: Any necessary calculations to support your design, such as stress analysis or material selection.
Final Product (if required): In some cases, you may be required to build a physical prototype or model of your design. SANS Standards Adherence to SANS standards is crucial for ensuring clarity, consistency, and accuracy in your drawings. Key SANS standards to be familiar with include: SANS 10111: Technical drawings – General principles of presentation SANS 10111-10: Technical drawings – Part 10: Lettering SANS 10111-16: Technical drawings – Part 16: Line types
