a 3D representation of an object where sides are drawn at 30 degrees

measurements on a drawing to show the exact size of parts

a dashed line that marks the middle of a hole or a symmetrical part of an object

Interpret orthographic projections

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.

Communication

What is the type of drawing that is used to represent a three-dimensional object in two dimensions?

Which views of an object are included in an orthographic drawing?

An {{ }} drawing is a 3D style  that shows multiple sides of an object at once.

The 3 views for an orthographic drawing are not separate drawings and connect together.

What term is given to the measurements you add to a drawing to show the exact size of each part?

The rules for creating an orthographic drawing are called {{ }} conventions.

A {{ }} point is a point where all lines in a one-point perspective drawing meet.

One point perspective is a way of drawing in 2D.

How do the objects closer to the viewer appear in one point perspective drawings?

What is the term given to the illusion of distance or three-dimensional space on a flat surface?

What do you need to draw before starting a one point perspective drawing?

When was one point perspective drawing first seen?
