Due: Start of Class 9/21
Chapter 12: Construct the following shapes found on pages 160-161 on size A (8 ½ x 11) sheets,
one per sheet. Select the scale that best fits the problem to the sheet. Mark all
points of tangency and strive for good line quality. Problem 13 (Five-Lobe Knob),
problem 14 (Walkway), and problem 22 (Lever Crank). In addition, use AutoCAD

Each drawing should have a "Title Block", simply put your name, assignment number, drawing
title, scale, and date in neat drafting style lettering. Don't worry about putting a box around it,
just keep things neat. Remember the grading policy:
