A tool to change conformation

This video and the accompanying molecular model will help you visualize a structure after a bond rotation. The initial conformation matches the left-hand line-angle drawing. Each click will rotate the indicated bond by 30 degrees. Try to find a way to make the 3D model identical to the right-hand structure in which all of the carbon atoms are in the plane. If you get stuck, watch the video.
