Rugged radius smoothening in Bezier curve

I apologize if I am in the wrong category or if this is a duplicate question. I did try to search for answers on this topic, to no avail.

I am, for the first time, trying to use Bezier curves instead of NURBS curves, as I need straight turns in certain parts. However, the radius isn’t interpolating properly, with obvious edges or “hills” where control points are.
Changing the interpolation method only worsens results.

Does anybody know how I can fix this issue?

Here is the blend file. If possible, I would like the curve to keep the overall shape of the mesh HR.010.
Thank you in advance.

You have to turn off “smooth” for the curve that uses HR.010 and maybe increase resolution afterwards a bit.
Or a bit tricky support the sharp one with additional control points.

Unfortanly it seems the smooth is not taken over to the curve.

Sorry, I don’t think I understand… the curve isn’t really using HR.010, I simply used HR.010 as reference when modeling the curve.
I’m not sure which ‘Smooth’ parameter you’re referring to, but if it’s the one in the Active Spline tab I don’t think that will help, since all it does is turn off smooth shading.
Increasing the resolution is also not changing results.

You mean the curve ‘bevel sharp’? Subdividing it isn’t really helping either.

Turn off smooth for “BezierCurve.002” that one that uses “HR.010”.
Than you can increase resolution of “HR.010” to make it more “smooth”.

The other way is to make support segements for the sharp points.
