I could not find a function for creating a fully parametric 3D polyline where I can set the radius per node. The obvious "Draft wire" made a 3D polyline but did not change when I changed the points I first created.
Or did I search for elephants?

Why don't you use the Sketcher? There you can use constraints for such things.

This topic headline says "3D polyline with radii". The Sketcher is 2D.

When all the radii are the same you can in the property box fill in a value for "Fillet radius"

Brilliant! And the radii are all in the right places. Then it's "just" a matter of making it possible to have different radii on each corner and following the points when one change them (parametric in my world).
Anyone against me creating a Feature Request about this?

[Pauvres_honteux]

Just came up with a "nice-to-have" feature for 3D-polyline: make it follow your surface of choice - Polyline on support.
In my world, internally, it should work in the same way as "Line on support", just in a coupled way.

in this picture no support were chosen.

Option "polygonal" of InterpolationCurve (CurvWb) makes a parametric polyline. But doesn't have the radii feature. Maybe ask Chris to add that to interpolationCurve?

I've made a feature request for the 3D polyline with separate radii on each "corner", see: issue #4240
