Deck 6: Three-View Drawings

Question 1

Explain how a side view is developed.

Answer 1

A side view is developed in much the same way that the other two views were obtained. That is, the draftsperson imagines the view of the object from the side that is to be drawn. This person then proceeds to draw the object as it would appear if parallel rays were projected upon a vertical plane.

Question 2

What is a working drawing?

Answer 2

An actual drawing of a part shows only the top, front, and right-side views without the imaginary transparent planes. These views show the exact shape and size of the object and define the relationship of one view to another. A drawing, when completely dimensioned and with necessary notes added, is called a working drawing because it furnishes all the information required to construct the object.

Question 3

Explain how a top view is developed.

Answer 3

To draw a top view, the draftsperson goes through a process similar to that required to obtain the front view. However, instead of looking squarely at the front of the object, the view is seen from a point directly above it. When the horizontal plane on which the top view is projected is rotated so that it is in a vertical plane, the front and top views are in their proper relationship. In other words, the top view is always placed immediately above and in line with the front view.
