COMMUNICATIONG INFORMATION - ISOMETRIC PROJECTIONS

Isometric Projections ~ a pictorial projection of a solid object on a plane surface drawn so that all vertical lines remain vertical and of true scale length, all horizontal lines are drawn at an angle of 30º and are of true scale length therefore scale measurements can be taken on the vertical and 30º lines but cannot be taken on any other inclined line.

A similar drawing can be produced using an angle of 45 for all horizontal lines and is called an Axonometric Projection
