A set of the three most common French curves, also known as a Burmester set. The bottom object is most commonly used for hyperbolas; the smaller one above it is suited for ellipses. The large one is used mostly for parabolas. [1] A French curve is a template usually made from metal, wood or plastic composed of
Primary among these are the compasses, used for drawing arcs and circles, and the French curve, for drawing curves. A spline is a rubber coated articulated metal that can be manually bent to most curves. Drafting templates assist the drafter with creating recurring objects in a drawing without having to reproduce the object from scratch every time.
French curves are used for drawing curves which cannot be drawn with compasses. A faint freehand curve is first drawn through the known points; the longest possible curve that coincides exactly with the freehand curve is then found out from the French curves. Finally, a neat continuous curve is drawn with the aid of the French curves.

An equation was given for various drafting tools, such as the triangle being x=ay, the compass being X²+y²=r² and a longer equation for french curves. I would be very interested to learn about how these equations function with the traditional real-world french curve template for example. Lots to be said about french curves!
