i was wondering how i could make a perfect spiral between two circles above eachother. both circles are the same with the radius. I want to divide the circles and then make a spiral between. And i want to connect those divided points to eachother. So it will be a ramp that is circular. I used the component Nurbs curve, but that component doesnt make a curve perfect between the circles, but a little in between. I will attach the file.

Use Interpolate (IntCrv) instead.
Nurbs curve uses the vertices as the control points.
Edit: Actually Interpolate(t) gives a better result following the circles. The other one gives a slight deviation at the ends of the curve.

hello, how to make a pitch spiral of 3550 mm and 418º?
It is something that a client sent from an online program, but I realize that I do not know how to do this type of spiral.
You can use polar array, move for each step and dome basics maths. I am sure there are scripts available for things like that.
Hello I hope this is understood.
you just need to find the start of the and then the spin number and use the native rhino command Helix

thanks it seems to be what I’m looking for, but I still can’t make it work I think it is necessary to somehow extend the 58 degrees shown by the helix

That solved it! Thank you very much!
Thanks for the complement! I’ll be showing progress @seghierkhaled
