How to draw medicine pills in adobe illustrator

For a diagram I was asked to do recently, I needed a pile of pills and realised I didn't know how to draw in 3D. So I have just worked it out by trial and error. First mistake I made was to try the effect on a whole pill when in actual fact I needed half a pill. Then I realised I needed to 3D revolve around the right edge, not the left. Finally when I tried to rotate my pill I got something like a centrifuge rotor so I tried changing the Z-axis as well as the Y and finally had what I needed to create my drawing.
