If a directrix line in the form of a cylindrical helical line of constant lead is given, and the axis of the cone is parallel to the axis of the helix, then an open helicoid will be generated. An open helicoid is the most known surface of constant slope. An open helicoid can be formed if one will take an evolvent of the circumference as a directrix curve.
