TWO POINT PERSPECTIVEinduction

Two Point Perspectives

Two Point Perspectives are one of the forms of 3D views that you need to know about in the Standard Grade Graphic Communication course.

This type of drawing is a sketch which shows the length, breadth, and height of the object being drawn.

A Two Point Perspective view is normally drawn with a corner closest to the viewer, although the view can change considerably depending on where the viewpoint is..

The viewpoint for the sketch can be above the object being drawn (usual position) or it can be level with the object or even below.

Two Point Perspectives

The positions of the vanishing points are always horizontal with each other and indicates the viewers eye level.

All vertical lines are drawn vertically but all angled lines need to be drawn back to meet at the Vanishing Points on the drawing.

Only the vertical line at the front edge of the view would ever be measured accurately. None of the other lines can be measured – this is why you need to sketch this type of drawing.

Two Point Perspective drawings are used in Graphics because this type of drawing looks realistic. It is a style of drawing which shows the object as close as possible to how we see it in real life.

Two Point Perspectives

If you are sitting an SQA Graphic Communication exam, you will be required to know how to draw Two Point Perspectives.

This type of drawing has always been included in the final paper every year, sometimes in the General paper and other years in the Credit paper.

The table on the following slide shows when each drawing was used and how many marks were allocated to it.

As you will see it is usual for buildings and furniture to be used as a subject in Two Point Perspective drawings although other objects can also be included.

USEFUL PRESENTATIONSBehind every orange box on this page is a presentation which you should watch. They will help you in a couple of ways.

They could be used to confirm that your understanding of a topic is correct.

They could also be used to guide you in the topics which you found difficult in class the first time round. They are designed as self help. Go through them slowly and if you still don’t get it, go back to your teacher as soon as possible.
