Introduction to Drawing Techniques: Lines, Shapes and Projections - JSS2 Basic technology Lesson Note

Drawing techniques form the foundation of architectural representation:

• Lines: Used to outline shapes, define edges, and indicate dimensions (e.g., continuous lines for outlines, dashed lines for hidden features).
• Shapes: Basic geometric forms (e.g., circles, rectangles) depict building elements and spatial arrangements.
• Projections: Techniques like orthographic projection show objects from different views (plan, elevation, section), aiding in comprehensive representation and construction understanding.
