Follow-me twist problem

And why not use Curviloft for propagate some profils on rails?

And the winner is ... Curviloft

Excellent solution pilou. Thank you v much. The perfect shape and a perfect solid with no complex intersections to fix.

Should fit snuggly against this lovely little Edwardian engagement ring.

Thanks again, everyone.

If you are doing a lot of jewelry it would be well worth your time to look into using vertex tools and true bend. It makes it easy to create rings from non symmetric geometry. And you can be as detailed as you need as long as you model cleanly. This required no cleanup after the bend except the removal of the double inner faces at the join. I only used 96 segments but you can easily go to the 200 you were using if need be.

Hi again,

Upon closer inspection, although the solidness is good and the profile alignment is good along all of the "straight" section of the rail, using Curviloft, the profile does twist on the shaped part of the rail. Back to TrueBend and solid-fixing. Scaling up x1000 reduced the errors to only 3 ... phew.

Just thought you might like to know.

Maybe we can try something...
Post the file of Profils and Rails in dxf format and let see that Moi3D (nurbs) will made as result in SKP format export...

...not sure...of the result (it's not your file just a test)

Here the structure of export SKP

Reloaded in SU

I must ask more polygons in export! (rendered as SKP file)

This time edges are perfect! (for an SKP file)
