3.3 Designing and making principles

Develop, communicate, record and justify design ideas using a range of appropriate techniques such as:

• freehand sketching, isometric and perspective

• 2D and 3D drawings

• system and schematic diagrams

• annotated drawings that explain detailed development or the conceptual stages of designing

• exploded diagrams to show constructional detail or assembly

• working drawings: 3rd angle orthographic, using conventions, dimensions and drawn to scale

• audio and visual recordings in support of aspects of designing: eg interviews with client or users

• mathematical modelling

• computer based tools

• modelling: working directly with materials and components, eg card modelling, producing a toile when designing garments, constructing a circuit using breadboard.
