Engineering drawing 5.1 Engineering drawing (introduction)
Figure 5.1(a) shows a drawing of a simple clamp. This is a pictorial drawing. It is very easy to see what has been drawn, even to people who have not been taught how to read an engineering drawing. Unfortunately such drawings have only a limited use in engineering. If you try to put
this drawing it would become very cluttered and difﬁcult to interpret. Therefore we use a system called orthographic drawing when we make engineering drawings.
