Hello
I have a design of a chandelier that has a low shape like a half sphere, I want to dress this shape with some kind of 8 leaf (a 3D print)
I would like to have the shapes unfolded so that I can print them

Hello @Farouk ,
I don't know how you made your play. But to unfold it, you would have to go through the sheet metal module, then convert your part into sheet metal (the logo 
) and finally click on unfold (the logo 
)
On the other hand, if you are on a complete Ø without an opening, it seems complicated to me. The software is not going to know where to start and where to stop

The basic problem is that a (portion) of a sphere is not foldable.
Why would you want to flatten them to do 3D printing?

stefbeno is right, you can't unfold a shape that is not feasible with a bending machine or a bending machine with SW. On the other hand, yes, you can make a spherical shape from a sheet of metal with an industrial process - stamping or spinning with a lathe - but the stock (dimension of the sheet) for these shapes is calculated by a human with know-how. There are also manual processes, hammer forming, the English wheel, etc.
This is a bit of a recurring question on the forum.
Second thing, why do a flat of your part if it's to 3D print it?
Heat it up and then shape it? Printing it in TPU? Not having to put a support?

Hello @coin37coin thank you for your answer
I didn't manage to do it in sheet metal, there are two winding directions
Hello @stefbeno and @Le_Bidule and thank you for your answers
My bad I made a mistake it's 2D printing (an arm robot with an extruder at the extimacy, PLA material...)
I somehow managed to get the unfolded shape out without calculation, I wanted to know if Solidworks could provide me directly with the shape (as for the sheets)
Or is there another software that allows you to use a sketch to have a result like this one for roughly spherical shapes
Thank you
Maybe more oriented towards modules that treat fabrics and leather, but I don't remember if SW has one.
Lead to dig.

If you do it in several quarters (principle of a world map) it is possible in surface to unfold a surface, even a spherical one for example.

Hello @ronathan and thank you for your answer, is there a special procedure to do or do I need to know the basics of surface functions?
Thank you
No, nothing special, you just have to think about dividing your surface into several parts and possibly doing some real forming tests. Otherwise you use the surface tools to create your model and then you use the "Surface Flattened" function
