Any curve to optimal arcs

Nice problem to be solved and very interesting approaches. Maybe I may add this one (not by me, but by Martin Siegrist @martinsiegrist):

Converting Curve to Arcs (with rounding arc radius)

Hi, I’m trying to convert 2D nurbs curve to series of arcs, but the arc radius has to be rounded to a multiple of 100mm due to construction requirement. (I’ve attached the nurbs curves sample I would like to convert) curves.3dm (93.7 KB) Also, I would like to be able to control the number of arcs. I’ve read through some of the discussions I could find in the forums, but non of them seems to work with this radius limitation. I like how Fred made an optimization for the positions of segments …
