Demonstrating Orthographic Projection

Abstract

Teachers of technical drawing often find difficulty in conveying the positioning, meaning and understanding of orthographic projection. This is not surprising since a solid object has to be portrayed in a certain accepted manner on a plane surface. The use of the terms ‘1st and 3rd angle’ or ‘British and American’ confuses matters, while auxiliary views add a further complication.
