Cross-sectional drawings

Design and technology

Pupils will develop knowledge and skills of communication, including freehand 3D sketching using the crating technique. They will learn how to render to show texture and tone. They will also learn how to draw using more formal techniques, such as one-point perspective and orthographic projection.
