braid on round surface

[AC Design]

Good evening to the whole forum!
I have a question about a problem that is bothering me.. I had to create a braid ring, where the three threads, melted in three different holes, are interwoven to form, precisely, a braid.

first I studied and reported the curves on the plane, paving the surface of the internal measurement and working on it. I gave the movement to the curves always on the plane and then, through the comendo _flowalongsrf I brought them to the surface. Now the problem is as follows:

as you will see in the attachment, the sweeo obtained from the curves applied to the srf round, should be the half-work to find, with the solid offset on two sides, the final thickness.
the curves have the right transversally to the srf, but not longitudinally, where they are arranged in such a way that I have the maximum and minimum thickness formed by the same surfaces that do not allow me to make the offset without obtaining the solids that go to finish inside the internal measure and too out of the external thickness.

I hope I've been clear.... you know I don't understand either!!

place these surfaces with two blue surfaces that should be the thickness inside which the surfaces should develop.

thanks in advance. I'm sure it's gonna be silly, but right now, I'm not getting there. .

Good evening to all,

ehmmm... Can you post an image of something like that already made?
:biggrin: I understood little and maybe an image helps

ps: is the section of the individual tresses circular or rectangular?

Hello mariuss!! Fortunately, after a night in white, I solved. ..I was looking at setting the height of surfaces compared to the surface to be taken as sample for the _flow.

I still found the solkution from your response to an old post where it was about a drill ring.

thanks anyway!:finger:

Hello, Mariuss. .
Nothing, I got stuck. ...see if I can explain! :smile:

in the file that I attached, in red there are the guidelines, or better, the maximum ongoumen that will have to have the braid.

in white you will see the floor surfaces that I used for realization. I did the solids and applied them on the surface with the _flowalongsurface command.
The braid you see applied is the first I developed, but it has the same size... I'd need it to follow the two red surfaces...

I thought I'd handle them on the floor, crushing them on both sides, but I still deform it.

Do you have any leads?

thanks in advance,m
