Orthographic Views

Orthographic (ortho) views are two-dimensional drawings used to represent or describe a three-dimensional object. The ortho views represent the exact shape of an object seen from one side at a time as you are looking perpendicularly to it without showing any depth to the object.

Primarily, three ortho views (top, front, and right) adequately depict the necessary information to illustrate the object. Sometimes, only two ortho views are needed as in a cylinder. The diameter of the cylinder and its length are the only dimension information needed to complete the drawing. A sphere only needs the diameter. It is the same from all angles and remains a perfect circle in the iso drawing.

The "six" side method is a process of making six primary ortho views that represent the entire image. This method gives you all the information to create the object from different isometric views.
