1.14 - Communicate ideas & information

2D communication methods

• Freehand sketching — quick ideation

• Orthographic drawing — precise 2D views for manufacture

• Sectional views — shows internal features

• Diagrams, charts and graphs — data communication

3D communication methods

• Isometric drawing — 3D without perspective, uses 30° angles

• Perspective drawing — 1-point, 2-point perspective for realism

• Exploded views — shows assembly

• Rendered 3D CAD models — photorealistic digital visuals

Presentation techniques

• Mood boards — style and aesthetic direction

• Presentation boards — summarise design proposals visually

• Physical models — tangible communication tool

• Digital presentations — CAD renders, animations, VR walkthroughs

• Storyboards — show product in use over time

Choosing the right method

• Client presentations — rendered visuals, physical models, mood boards

• Manufacturer — detailed orthographic drawings, tolerances, BOM

• User testing — working prototype or realistic appearance model

• Early ideation — quick freehand sketches and annotations
