GCSE DT RevisionDesign Communication and Presentation
Key facts
Sketching and developing ideas
- Freehand sketching — quick, flexible idea generation. Not to scale, not fully accurate, but fast.
- Annotation — notes on sketches explaining materials, dimensions, how it works, design decisions. Essential for communication.
- Rendering — tone, shading and colour added to sketches to communicate 3D form and material appearance.
- Crating — drawing a box first to aid construction of 3D shapes in sketching.
- Designers use quick sketches early for exploration, moving to detailed drawings and CAD as designs develop.
Different audiences need different presentations
- Client / investor — rendered perspective drawings, 3D CAD visualisations, mood boards. Focus on aesthetics, context, appeal. Minimal technical detail.
- Manufacturer — fully dimensioned orthographic working drawings with tolerances, materials, surface finish, assembly information.
- User instructions — clear, simple illustrated steps. Often no text or simple language. Understood without language (IKEA style).
- Mood board — collection of images, colours, materials and textures communicating a design direction or brand identity.

1 markAnnotation purposeAQA 8552 style
Why is annotation important when presenting design sketches?
A It makes the sketch look more professional and artistic
B It communicates the designer's thinking — materials, dimensions, how it works — that the drawing alone cannot show
C It allows the client to correct the drawing without speaking to the designer
D Annotation is only needed on orthographic working drawings, not concept sketches
1 markWorking drawing vs rendered sketchAQA 8552 style
Why does a designer send a working drawing rather than a rendered perspective sketch to a manufacturer?
A Rendered sketches cannot show colour
B A working drawing includes exact dimensions, tolerances, materials and surface finishes needed for manufacture — a rendered sketch does not
C Manufacturers prefer hand-drawn sketches to computer drawings
D Rendered drawings always contain errors
4 marksCommunication for client vs manufacturerAQA 8552 style
Describe how a designer would communicate a new desk lamp design differently to (a) a client investor and (b) the manufacturer. (4 marks)
Hint: (a) Client: aesthetics, renders, mood board — no complex technical detail. (b) Manufacturer: orthographic, dimensions, tolerances, materials, assembly. Both answers need specific detail.
