What Technical Drawing covers

Technical Drawing in Electronics Engineering Level 6 teaches you to produce and read the drawings that electrical and electronic work depends on. You prepare drawing equipment and materials, caring for them as the manufacturer and workplace require. Plane geometry drawings cover lines, freehand lettering, borders and title blocks, angles, bisection, geometric figures, pattern development and tangents. Pictorial and orthographic drawings add symbols, freehand sketching, orthographic elevations, isometric and oblique views. Two AutoCAD outcomes cover basic operations and developing 2D drawings. The last outcome is electrical drawings: symbols, block, schematic, circuit, line and wiring diagrams, simulation and placing components in a building plan.

Careers after Technical Drawing

Electronics engineering drawings are the language that turns ideas into real, working hardware. Whether you end up in a bustling factory, a field-service team, or running your own design studio, the ability to produce clear, standards-compliant sketches and CAD models will open doors across Kenya’s growing tech landscape.

  • Electronics manufacturing workshops in industrial parks (e.g., Kiambu, Thika) - you select the right drafting pens, templates and paper, keep the equipment calibrated, and produce detailed 2-D layouts of circuit boards and enclosures, earning a steady wage as a production drafter.
  • Telecommunications infrastructure firms installing cell-tower equipment in Nairobi and regional counties - you generate first- and third-angle orthographic drawings of antenna mounts, cable trays and power supplies, helping the team win contracts and receiving project-based pay.
  • Solar-PV installation companies setting up solar farms in Garissa or Turkana - you create precise wiring diagrams and panel mounting sketches, ensuring safe, efficient installations and earning a salary as a design technician.
  • Medical-device assembly units in Nairobi’s industrial zones - you interpret symbols and abbreviations to produce compliant drawings for diagnostic equipment housings, supporting quality-assurance processes and receiving professional remuneration.
  • Automotive-electronics retrofit shops in Mombasa’s port area - you freehand sketch and dimension custom control panels for trucks and buses, enabling the shop to offer bespoke upgrades and charge premium service fees.
  • E-waste recycling centres in Nairobi and Kisumu - you apply safe waste-disposal procedures for drafting scraps, inks and plastic templates, helping the centre meet environmental regulations while earning a salary as a compliance officer.
  • Freelance CAD drafting services operating online from any town - you use AutoCAD ribbon, navigation and status-bar tools to deliver client-specific drawings worldwide, billing per drawing or per hour and building an independent income stream.
  • Technical training institutes offering short courses in Nairobi’s suburbs - you demonstrate proper use and maintenance of drawing equipment, earning income as an instructor or consultant while raising the skill level of future engineers.
  • Small-scale electronics design studios in Nakuru or Eldoret - you produce first-angle orthographic sketches for prototype enclosures, allowing the studio to pitch to investors and share in the venture’s profits.
  • County-level road-lighting projects across Kenya’s districts - you draft layout plans for lighting poles, control cabinets and wiring routes, ensuring compliance with standards and receiving project-based remuneration.
  • Construction firms building smart homes in coastal resorts (Mombasa, Diani) - you generate pictorial sketches of integrated home-automation panels, helping the firm market high-tech residences and paying you as a specialist drafter.

Mastering technical drawing gives you the passport to design, build and innovate across Kenya’s most dynamic sectors - turn your sketches into a thriving career!
