  • Oblong - enter the length and width of the oblong.
  • Sine wave - enter the length of the wave and its amplitude. - And the same for the cosine wave.
  • Lissajous curve - also known as Lissajous figure or Bowditch curve - enter the amplitude, and other parameters.
  • Parabola - pick the points that define it. [the 3 points that define the shape (and one or two more points to trim and extend it)].
  • Catenary curve - defined by the two end points, and its length (which must be greater than the distance between the ends).
  • Spirograph curve - with lots of parameters like the base diameter, the rotating circle radius and the drawing pen position radius, etc.
  • A simple spiral, with starting radius and ending radius.
  • Helix with a constant radius, and several turns, a figure that resembles a spring.
  • Conic helix, with the starting and ending radiuses, and its height.
