What Technical Drawing covers

Technical Drawing in Electrical Engineering Level 6 takes a learner from drawing equipment to electrical diagrams produced in AutoCAD. Care of equipment and materials comes first, then line types, freehand lettering, border lines, title blocks, angle constructions, tangents and pattern development. Pictorial and orthographic work adds symbols and abbreviations, freehand sketches, elevations, isometric and oblique views. Two AutoCAD outcomes set up the interface, ribbon and status bar tools, navigation, layouts, 2D creation and editing, and file saving. The final outcome draws block, schematic, circuit, line and wiring diagrams, simulates them and places electrical components on a building plan.

Careers after Technical Drawing

Technical Drawing opens doors for a Level 6 electrical graduate wherever installations need plans before work starts, whether those plans are on paper or on a screen.

  • Electrical design consultancies in Nairobi - draw schematics in AutoCAD and simulate electrical and electronic drawings before installation.
  • Estate and housing developers in Nyeri - turn architectural plans into drawings showing where electrical components go, using standard electrical symbols, layouts and the correct file format for sharing.
  • Technical drawing sections of workshops in Kakamega - produce pictorial and orthographic drawings of components, sketch geometric forms freehand and develop patterns for fabrication.

  • Drawing services for small builders in Machakos - offer paid sketches and 2D drawings with correct layouts, symbols and file formats.

  • Equipment makers in Thika - read pictorial drawings and symbols to build and check components.

The grounding in plane geometry and standard conventions supports every role, and the AutoCAD skills transfer between employers.
