This KS3 Design and Technology quiz takes a look at communicating ideas. Drawings are a great way of communicating ideas. Having an idea is one thing. Developing the idea and getting it across to others is another. The usual first step in the design process are thumbnail sketches. These small and very rough drawings are produced rapidly and only show the essential ideas of the design. They are very useful for exploring several alternatives before deciding on which is likely to be the best way forward. The other drawings are all developed from these initial sketches, and finally, a prototype can be produced from the working drawing.
Designers will produce presentation drawings to show the final design to their customers. There are many different techniques for producing these and other drawings. In order to communicate a three dimensional idea, an isometric view or a perspective drawing is used.

Just like the grid of a computer graphics program, grid paper helps you get everything in the right place

Each of these elements can make the different features easier to understand and visualise
