Cross-sectional drawings

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.

Communication

to show all the parts separated but in the correct positions

What is the purpose of an exploded diagram?

A dashed line that shows the middle of a hole or symmetrical part is called a {{}}.

keeps the parts visually organised and readable

shows the assembly layout, horizontally or vertically

Match the feature to its purpose in an exploded diagram:

An exploded diagram can be drawn vertically or {{}} depending on the design.

a drawing made by hand without using a ruler

Adding light and dark areas to a drawing helps create __________.

adds colour, texture or tone to a drawing

to show what a product looks like from above

to show depth by using a single vanishing point

An {{}} drawing uses labels to explain parts of the design.

What do we use to show texture and surface detail in a drawing?
