Abstract
This chapter discusses the helix, which is the path traced by a point moving uniformly around the surface of a right cylinder that is moving axially. The ratio of the speeds of the point and the cylinder is constant. For the construction of a helix, all lines must be construction or projection lines until the curve is drawn in outline. The chapter discusses the construction of a helical groove in a cylinder. The chapter describes an ellipse as the front elevation of a circle at any position between the vertical and horizontal planes when rotated about its horizontal axis. The chapter illustrates ellipses whose major axes are approximately twice the minor axes. There are several ways of drawing an ellipse.
