# Perspective Drawing

### Why do this problem?

Representing 3D objects in two dimensions on paper is a vital skill in the Design Technology curriculum, as well as an aspect of Shape and Space in the Maths curriculum.  This problem is part of a set of problems which will help students to understand why there are different ways to represent a 3D object in two dimensions, and what maths lies behind each method.

The article 3D Drawing was written to support these problems.

### Key questions

What are the advantages of this method of 3D drawing?  What are the disadvantages?

What features of the object are retained in the drawing, which are not?

### Possible extension

Challenge students to do a perspective drawing of the structure from a different perspective!  (They should do a sketch first to ensure they know which cubes will be visible).

### Possible support

Perspective drawing is much more difficult to do accurately than either oblique projection or isometric.  Students who find it difficult to draw the multi-link structure shown in the problem could be given simpler multi-link structures to draw, helping them to build up to drawing more complex ones.
