elliptical shape reticular creation

[Mircaccio90]

Good morning to all, I am in trouble to realize the outside of this contract for a customer who needs the model by tomorrow. I have tried various ways, from wraps to create a face on the surface but unfortunately it does not come, because it deforms the sketch, or unfortunately straight with winds can not make the command start. I thought I'd try with a 3d sketch, do you have advice?

coils work on closed contours. also works on single-curve surfaces, in case you can use it you wouldn't have the game of plot reduction to the poles.
I would draw the plot of a vertical line, then with angular repetition the copier n times.
the vertical line would sketch it for successive steps so as to see from time to time the overall effect with repetition.
in brief:
1: Make a strip
2: Coptics with angular repetition
3: If it's not okay, go back up and change the strip.

Would you strip it in a 3d sketch or just 2d more wraps? a colleague of mine gave me the maximum use of a sheet, which could be a great idea..

I would not use winds because it has limits in the management of contours. with a sheet you would still not have a double curvature effect as is the egg pattern of the cover. This does not take away that, if the crushing of the cloak falls back into tolerance, it is a viable solution. Perhaps a solution can be to draw the strip in the plane and project it, in a context of 3d sketch, on the theoretical ovoid. I can't help you any more for lack of time, besides not having clear the final effect you want to get.

However, I trust that those who know more about me can intervene so that everyone can learn something more.

the sheet is not feasible.
the process would require a partial slice of the toroid made or converted into sheet metal, distension, cutting of the silhouettes, folding. Unfortunately that would not be a folded sheet, but imbutted and this does not allow development.
you can still try by modeling a partial slice of the toroid by sweeping (circus of the 105 circle (viewed in pdf plant) as a profile hesemielisse as a path.
made the sweep drawings on a tangent plane the profiling to be cut, well quoted, and then in the command uses the wrap method. systems the sketch of profiling until it is satisfied.
repeat the slice enough

would also be useful for everyone, as well as welcome, that you update the discussion you opened, https://www.cad3d.it/forum1/threads/solidworks-2017-e-sweep-creati-su-elica.53764/#post-419892, saying if and how you solved the problem

Maybe you'll tell us how you did it.
