Unit Description and General Aims

Professional engineers and engineering technologists need to be able to communicate complex technical details of products to various stakeholders and hence sketching, engineering drawings and computer aided drafting are essential skills. This unit introduces students to engineering drawing and the use of computer-aided drafting tools starting with hand sketching and progressing to engineering drawings.

Learning Outcomes

On successful completion of this Unit, students are expected to be able to:

1. Use sketching and hand-drawing as a tool for visualization and communication
   Bloom's Level 3
2. Construct and read drawings in orthographic and isometric projections
   Bloom's Level 3
3. Interpret sectional views and working drawings
   Bloom's Level 5
4. Create solid models and technical drawings of simple, well-defined parts and assemblies using CAD tools
   Bloom's Level 6
5. Interpret and create simple engineering drawings and diagrams from different engineering contexts
   Bloom's Level 5
6. Develop design skills based on a structured design philosophy
   Bloom's Level 3

Student assessment

Overall requirements: Students must achieve a result of 50% or above in the exam itself to pass the exam, and must pass the exam to be able to pass the unit. An overall final unit score of 50% or above must be achieved to pass the unit once all assessment, including the exam, has been completed.
