Now that your drawing plane is properly set up and you are in construction mode, click the Regular Polygon button and move your mouse along the edge of the left cylinder while holding down the CTRL button. You should see that it is snapping a small black dot either to the edge of the cylinder, or to the center of the cylinder, depending on where your mouse is along the circumference. Move so that the black dot snaps to the center of the cylinder and click the left mouse button. This places the center of the polygon at the center of the cylinder, the program prompts us for the number of edges on the polygon and the radius it is inscribed in. Investigating with the mouse a little bit looks like a radius of 30 is good (so type that in) and enter 14 for the number of side, but leave the Filled box unchecked this time. If you can't get the snap to lock onto the center of the cylinder (I had trouble with mine) you can always enter the coordinates manually (X=40, Y=0, Z=110). Add a second polygon, also centered on the left cylinder but this one should have 22 side and 45 mm radius. Finally add the same two polygons over the right cylinder (centered at X=100, Y=0, Z=110). When you are finished you should have two "figure-8's" surrounding the cylinders and head bolts. (Note that currently the program does not actually prompt you for the number of edges so you will just have to set the center and radius and then change the number of faces in the Property view).
