All questions and answers
Read through the full deck, or practise recalling each answer above.
Why are design solutions communicated to a third party?
Show answer
To demonstrate the design's suitability, so someone other than the designer (e.g. a client or manufacturer) can understand and evaluate it.
Why should design sketches include written notes?
Show answer
Notes explain what a drawing alone cannot show — materials, dimensions, functions and modifications — so a third party can judge the design's suitability.
Exploded drawing
Show answer
A drawing showing a product's components separated (pulled apart along their axes) to reveal how they fit and assemble.
Sketch modelling
Show answer
Quickly making rough 3D models from cheap materials (e.g. card, foam) to explore and communicate the form of an idea.
What is mathematical modelling used for when communicating a design?
Show answer
Using calculations (e.g. dimensions, quantities, forces, costs) to predict and demonstrate that a design will work before it is made.
What does a flow chart communicate about a design solution?
Show answer
The sequence of steps and decisions in a process, such as how a product is manufactured or how a system operates.
What is the advantage of a 3D sketch over a 2D sketch for communicating a design?
Show answer
It shows the overall form and how parts relate in space, so a third party can visualise the finished product.
What are constructional considerations when communicating a design?
Show answer
How the product will be built — its joints, fixings, materials and order of assembly.
