Outline Spline

This function can be used to trace splines with a circumferential spline curve and thus map them thicker. This turns a straight line into a rectangle. Similar to the Thicken function for polygon geometry, this Node also lets you define where the center line of the outline should be relative to the original spline. In addition, when thickening an open spline, the end connections can be designed differently or omitted completely. The following video shows an example of how to use the Node. There, the radii of various arc splines were animated and then outlines of these splines were extruded.
