Chapters: 3
1. Seeing, observing, experimenting
Observation and technical drawing
- Technical Drawing: Communicating Design Ideas – Technical drawing is a shared visual language for showing the exact shape and size of an object. Designers start with freehand sketches, then use pictorial views (isometric, oblique) to show the object in 3D, and orthographic projection (front, top and side views) with standard lines, dimensions in millimetres and a scale so that anyone can make it. Today most drawings are made with CAD software.
2. Predicting, imagining, designing
Planning and design
- The Design Process: From Problem to Product – The design process is a loop of steps designers use to solve a real problem for real people: investigate the need, define it in a brief and a measurable specification, generate many ideas, build a prototype, then test and evaluate it against the specification. Whatever fails sends you back round the loop. This repeating is called iteration, and it is how almost every product, app, building and artwork is improved.
3. Intervening, transforming, producing
Making and repairing
- Making and Repairing Things – To repair something, follow a loop: look at what is wrong, test one part at a time, make it safe (power off), take it apart carefully, fix the faulty part, put it back and test again. Regular care, called maintenance, stops many faults before they start. The same careful steps help when you build something new from everyday materials.
