Explanation:
There are 6 principal views in an orthographic projection. These views include the front, top, right side, left side, bottom, and back views of the object being projected. Each view provides a different perspective of the object, allowing for a comprehensive understanding of its shape and dimensions. However, it's most common to use three principal views (front, top, and right or left side view) to fully describe the shape and size of an object. This is known as the three-view orthographic projection.
