Wrapping a Pattern on a Hyperboloid

3D Design Volume Model

Hello

After skimming the fofo, I unfortunately didn't find a solution to my problem. I will explain my problem as briefly as possible:

I have a slimmed cylinder in the middle (something roughly like a hyperboloid) and I 'd like to wrap a pattern around it that covers it 360°.

The problem is that if I use the surface winding function, the pattern doesn't stay horizontal because my part is not a real cylinder.

To better understand, here is (in 1st) what I get against what I would like to get (in 2nd):

 

So I would like you to enlighten me on how to proceed so that the pattern that I will be rolling up remains horizontal.

(I specify that my pattern is more complex, the rolled band on the photo is only there for the example.)

Thank you in advance for your help.

Hello

Which version are you in and can you share your file?

I'm working on the 2017 student version.

Here's my file.

Thank you

See if it's good; To achieve this, I created an axis in the center of your part, then a sketch of your profile  on the front plane and made a revolution of the profile following the axis on 180°, now it's up to you to adapt according to your needs...

Indeed, the problem seems to be solved for a simple reason such as a band. But if my pattern is more complex, I couldn't use the technique of revolution, could I?

Basically, the pattern I want to reproduce is the following:

I have already managed to roll up the sketch of this pattern on a cylinder, but on my piece I don't see how to do it, even with a revolution...

Thank you all the same.

Hello

I think you can get away with sweeping features by combining the curves projected on your hyperboloid face.

Also try to work as much as possible with symmetries or circular repetitions.

Combining the bodies after the fact will allow you to check the shapes independently. Well, it's one way of doing things.

I gave you an example.

Kind regards

I absolutely wanted to make a single sketch of the pattern and then roll it up but my stubbornness was useless because your solution seems to solve my problem and is not complicated to implement. In addition, your example allowed me to understand exactly how you proceeded.

Thank you very much for your help.
