"Now," said Ralph, "no shop drawing is complete unless it shows all the necessary dimensions; so I will put them on to show you how it is done, but after this you must dimension every drawing you make."
The finished drawing of the cylinder is shown at b.
Harry was told to make the mechanical drawing of a cone, 2 inches in diameter, and 3 inches high. While he was working at this problem, Ralph disappeared, and when he returned Harry asked where he had been.

"Never mind. Let me see your drawing," c ([Fig. 26]). "All right." Then he laid a little wooden object on the table.
"Why, it's a cat," said Harry.
"Yes, a tip cat, and as soon as you make a working drawing of it, you are going to manufacture one with your knife. Please notice that the tip cat is a cylinder with a cone at each end, and two views will show everything about it."
The drawing took longer to make than Harry imagined it would; or it seemed longer because he was so impatient to get to work with his knife. His finished drawing is shown at a ([Fig. 28]).
