Need some help. How to make smooth transition on my model

[Robert_Evt]

I’m using Rhino 9 and I don’t know how to create a smooth transition here:

This is my model in rhino 8 format:

Airplane_nose.3dm (1.3 MB)

(Tried fillet edge - it’s doesn’t work. Maybe Pipe + Trim + BlendSrf…)

FilletSrf should work if the radius is big enough to cover the gap on both sides.

Kyle’s solution of Pipe+Trim+Blend is always the sharpest solution.

_filletSrf with R=2.1

this very small radius / strong curvature in the section / at the end will make you a lot of trouble:

my first go would be to build something more like this:

and then use pipe trim as transition…
