Hello
I want to make a piece with several faces starting from a 3D sketch, I don't know which tool to use.
I tried using the extruded surface tool but it doesn't work.
I would simply like to fill my " triangles " with surfaces to determine the sheets, maybe even sheet metal with bending?
I'm attaching the 3D sketch if ever...
Thank you in advance to all those who take the time to help me.

Good evening @kevin.ramon
Happy to welcome you to the forum. 
I hope that we can help you solve some problems, but also that we can benefit from your knowledge and experience.
Kind regards
For your problem, it's quite simple.
After seeing that the smallest edge is 600 mm long for the folding, you will have to assemble it into two or three triangles.
It is necessary to determine the number of triangles that can be bent without too much material loss.
To do this, either you copy the different sketches that you assemble edge upon edge in a larger part or you turn your sketches into Blocks which can be easier to manipulate.
Anyway, given the size of the pieces, you won't be able to make many simultaneous folds.
If my explanations are not clear, I'll make you a mini TUTORIAL video
To everything'
Our super strong sheet metal colleagues will complete the process because there are several ways to get to what you want to do.
If our @ac_cobra_427 sticks to it, it won't make a fold.
To make this kind of block (hopper?) in sheet metal work in general I create a solid block extrusion then removal of material and then in an assembly I use it as a template by laying the sheets on the faces.
The sheet metal parts are thus linked to the block and if the block changes size for x reason the sheets too.
In general, never a part linked to another but for the hoppers I am an exception.
Thank you for your answers, I hadn't thought of making side plans to make an extrusion.
It is effectively a hopper between a Redler and a disc screen.
In my head I imagined the solution more simply by seeing my 3D sketch, that's why I went with the extruded surface tool but it doesn't work.
Thank you
