What Technical Drawing covers

Technical Drawing for Automotive Engineering Technology Level 6 teaches you to read and make the drawings that technicians use to describe components. It begins with drawing tools, equipment and materials and their upkeep, then plane geometry: types of lines, constructing, bisecting and measuring angles, plane geometric forms and scales. Orthographic drawing covers first and third angle projection, dimensioning, sectional views and freehand sketches. Solid geometry covers drawings of patterns, solids, development and interpenetration of solids, symbols and abbreviations, and auxiliary views. Isometric drawing includes curves, circles and oblique sketches, and the unit ends with assembly drawings with sectional views and parts lists.

Careers after Technical Drawing

In the world of automotive engineering, the ability to turn ideas into clear, accurate drawings is the bridge between imagination and a working vehicle. Whether you end up in a bustling workshop, a small-scale fabrication shop, or running your own design service, the skills you master in this unit will be the language you use every day to communicate with engineers, mechanics, and clients across Kenya.

  • Automotive design and drafting departments in vehicle assembly plants (e.g., Thika and Kiambu) - you produce orthographic and isometric drawings of chassis components, using the correct line conventions and scales, and earn a salary as a junior drafter or CAD technician.
  • Custom coach-building workshops in Mombasa’s port area - you sketch freehand and develop auxiliary and true-shape views of modified bodies, helping clients visualise upgrades and charging per project or per drawing set.
  • Spare-parts fabrication shops in Nakuru and Eldoret - you create precise section and pattern drawings of brackets, brackets, and brackets, allowing the metal-working team to cut and weld parts accurately; you are paid either a fixed wage or per-part drawing fee.
  • Vehicle inspection stations in county headquarters (e.g., Kisumu, Machakos) - you interpret and annotate inspection reports with accurate angle measurements, symbols, and section views, ensuring compliance and receiving a stipend or hourly rate for each inspected vehicle.
  • Small-scale 3D-printing enterprises in Nairobi’s tech hubs - you convert hand-sketched concepts into scaled orthographic and isometric drawings that feed directly into CAD software, earning income through design-to-print contracts.
  • Auto-body repair shops in Westlands and Kilimani - you produce quick-draw sketches of dented panels, using correct line types and bisected angles to guide panel-beating technicians, and receive a commission for each repair plan you provide.
  • Technical training institutes and TVET colleges in Kitale and Meru - you teach new learners how to identify drawing equipment, apply symbols, and construct geometric forms, earning a teaching salary while shaping the next generation of Kenyan drafter-technicians.
  • Engineering consultancy firms serving county road and transport projects - you develop detailed auxiliary views and oblique sketches of vehicle-related infrastructure (e.g., loading bays, service bays), billing clients on a consultancy-per-drawing basis.
  • Freelance drafting services for independent mechanics across rural Kenya - you travel to workshops, produce accurate scale drawings of locally fabricated parts, and charge a fee per drawing or a retainer for ongoing support.

Your mastery of technical drawing opens doors to many rewarding pathways - whether you prefer the steady rhythm of a large plant, the creative freedom of a custom shop, or the independence of running your own drafting business. Keep drawing, keep refining, and watch your sketches turn into the engines that drive Kenya forward.
