Summary

• Description:

  The PDF document comprises Grade 10 Woodwork Strand 4 Related Drawings Notes. The MS Word version (editable) is also available upon your request.

  It covers the following strands and sub-strands:

  • Strand 4.0: Related Drawings
    • Sub-strand 4.1: Drawing and Sketching
      • Introduction: Drawing as the "universal language" of technology that bridges the gap between design concepts and practical manufacturing.
      • Pictorial Drawings (3D Views):
        • Isometric Drawing: Uses 30-degree axes to show three sides of an object at once.
        • Oblique Drawing: Shows the front face true to shape, with depth lines at 45 degrees (Cavalier vs. Cabinet projection).
        • Perspective Drawing: Realistic representation where parallel lines converge at vanishing points (One-point and Two-point perspective).
      • Isometric Projection Techniques: Detailed steps for setting up axes (Vertical, Left 30°, Right 30°) and using the "Crating" or "Box" method to draw complex shapes.
      • Orthographic Projection (2D Views):
        • Principles: representing a 3D object using multiple 2D views (Front Elevation, Plan, and End Elevation).
        • First Angle Projection: The standard convention used in Kenya/UK, characterized by the specific layout of views and the projection symbol.
        • Dimensioning: Rules for placing extension lines, dimension lines, and arrows for clarity.
      • Freehand Sketching: Techniques for quick visual communication without rulers, focusing on proportion, line quality (thick vs. thin), and using the crating method for curves.
      • Computer Aided Design (CAD): Introduction to digital drafting, the shift from manual drawing boards to software (like AutoCAD/SketchUp), and benefits regarding speed, editing, and storage.
