Unit Aim
The aim of this unit is to provide Learners with technical drawing skills essential for design and construction-related fields. Learners develop proficiency in geometric constructions, orthographic and perspective drawing and the application of scale in technical representations. This unit focuses on linework, lettering, patterns and architectural styles to enhance visual communication. Through practical exercises, Learners refine their ability to create detailed, accurate and professional-quality drawings, in preparation for industry applications in design, drafting and construction.
