Wish there were some example files on Houdinigubbins, be amazing to explore all of those curve examples.

Hi,

here is an file (experimental state) using mostly the ideas from Ryan Juckett. 

Input are 4 points (polycurve) and it calculates the arcs and the necessary attributes. It seems to work in usual cases (but there some cases where it probably fails). It only works, if all points are on a plane.

I don't have an idea at the moment. This one ist only working for two points (with 2 tangents, which are controlled by the 2 other points). I don't think connecting/overlapping works here, because the arc is taking the shorter way. Maybe you can force the arcs to take the right way, if the first two arcs are calculated. But this will depend on user input etc... .
