“Before the term spline came to refer to a mathematical function producing smoothness (and subsequently, in design software, to a smooth curve with control points) it was once an actual physical drafting tool, a flexible metal or wood strip with weights used to hold the spline in place. This tool developed out of necessity to design smooth, aerodynamic forms and leveraged specific material properties . . .”
