Pictorials break down into two (2) groups  Group #1= Perspective or Central Projection.  Group #2= Parallel Projection that includes Orthographic (Multiview), Oblique, & Axonometric. 2 Copyright © Texas Education Agency, 2012. All rights reserved.

Group #1: Perspective Drawings  Perspective drawings produce the view that is most realistic.  A perspective drawing is often referred to being the “camera” or photo view.  There are three main types of perspective drawings depending on how many vanishing points are used.  These are called one-point, two-point, and three-point perspectives. 3 Copyright © Texas Education Agency, 2012.

Oblique Pictorials Oblique pictorials don’t look as realistic as perspectives or isometrics because the side or depth view looks distorted or “stretched out”. However, circular shapes in the front view aren’t distorted and that makes them easier to draw. If you do have to draw an oblique, cabinet projection is the method you use because the depth is halved making it look more realistic. 5 Copyright © Texas Education Agency, 2012.

Axonometric Projections  We are going to focus only on Isometric’s, but there are others.  There are three (3) types: Isometric: all angles are equal or 30 0. Dimetric: only the top & right side view are the same angles. Trimetric: none of the angles are equal. 6 Copyright © Texas Education Agency, 2012. All rights reserved.

Why draw Isometrics?  They are BOTH true size, or dimensionally correct, and visually pleasing to the eye.  Think of them as a combination of a perspective and an oblique drawing, using the best from each. 7 Copyright © Texas Education Agency, 2012. All rights reserved.
