Sketches show ideas quickly. Wireframe drawings can be made from simple shapes and 3D shapes can be used to make models from surface developments. Enhancement techniques, like texture and tone, are used to make a drawing look more realistic. Colour is important and the colour wheel can be used to design colour schemes. Graphs, charts, signs and symbols are used to graphically represent information.
Sketching
A sketch is a way of showing ideas quickly. It is done freehand, but a piece of grid paper may be useful.
Media
Pencils and fine-line markers are good graphic media for sketching. Some limited colour may be used on quick sketches.
Detail
A sketch is not a finished drawing. Sketches should be clear enough to allow other people to understand your ideas, but not show too much detail.
3D sketches
Sketches can also be simple 3D models to show spaces or moving parts. They will usually supplement paper-based sketches.
