How many view do you need Orthographic Projection? 1 2 3 As many as are needed

We need to ask ourselves what is Orthographic Projection? Basically it is a way a representing a3D object on a piece of paper. This means we make the object become2D. The difference between Orthographic Projection and any other drawing method is that we use several2D views of the object instead of a single view.

Orthographic Projection gives us a very clear method of communicating ideas and objects. It is a method that every engineer in the world recognizes. Because of this we can reproduce any object drawn Orthographically. This is very important.

Think of how many languages there are in the world... imagine how much of a problem this presents to designers and manufacturers across the world. Imagine an engineer in Germany who wants a plastic bottle manufactured in Japan. How do you think he will overcome the language barrier? The easiest way is to use a drawing. However drawing can be interpreted differently by different people. A good example is shown below. Is the blue face on the inside or outside of the box?

All of these problems can be overcome using Orthographic Projection. An engineer in Germany can have a plastic bottle made in Japan, exactly as he wants it, without any problem if he sends an Orthographic drawing of the bottle. This makes Orthographic Projection a Universal language among people in engineering professions!
