Simplify a polyline with concret radius?

[asdf1 (asdf)]

Hello good afternoon to everyone.

I’ve been trying to solve a problem I have with rhino for a few days and I would like to know if someone can help me.
I need to reconstruct the polyline in the image into arcs that have rounded radii.
I’ve tried putting circles with radii I’m interested in and then I wanted to join the ‘‘circle, tangent, tangent, radius’’ tool but I can’t get it to work.
I have also tried using the ‘‘convert curve to arcs’’ tool
but it gives me some radii that make it very difficult for me to manufacture the part.

I hope someone can help me

I have a little tool in my plugin Nautilus for Grasshopper (I didn’t implement it in Rhino) that converts a polyline to arcs and lines. So by choosing the tolerance you can have more or less arcs
here with a 9 tolerance 12 parts, 11 arcs

Thank you very much Laurent, this plugin looks very good, and I think it’s what I need, but I can’t install it, do you know why?

The RhinoCommon method might also work for you:
