1) Drawing 1 Use the following layers: -Use construction lines as follows:-Distance between horizontal center line and top of key way: 0.95 -Width of key way: 0.36 -Units are Engineering

with precision 0.0.00" and Inches. Step 1 Make the layers as desired. Step 2 Draw three circles with Dia. 1.5, 2.5, 4 and Radius 4 & 4.5 with center at the same point. Step 3 Draw vertical and horizontal lines and two inclined lines at 30° &150°Step 4 Draw offset lines @ 0.25 parallel to vertical and inclined lines. Step 4 Draw tangent lines to two outer and two inner circles as shown. Step 5 Draw circles with radius 0.25 at the intersection of circle with dia.4 and the vertical and inclined lines. Step 6 Draw six circles with radius 1.5 with center on the outer circle but midway between the lines intersecting the circle. Step 7 Draw a key way rectangle measuring .95 x. 36 with intersection the center of all the circles. -Place finished drawing in the title block and print the layout to the .pdf file -Write down your name and date in the title block before printing
