change face on boxed sheet

[graziano-g]

hello, it's definitely possible but I can't find the solution. . .
I would like to give a slope to the folds as highlighted in the following figures.
Does anyone have any ideas?
Thank you.

If you've done your hips with the flange of the edge, I have no way to see your file, change the sketch, remove the horizontal bond to the lower lie and quoti to pleasure

I didn't use that technique, I drew the profile so I extruded it then turned it into sheet metal. the flanges on board I made only the upper long edge, the closure of the channels and the rear appendages Should I do two sketches on two floors so make basic extrusion with loft then turn into sheet metal?

then remake with the side walls as flange from edge.
because to make a sheet you do first extrusion and then turn it into sheet metal; I would have understood if I had said that you had made the sheet straight from the profile to c, it happens to make a modeling approach and to realize that it was not the appropriate one, but as you did it is farce work.
maybe you could combine with a face move, but I'm not very convinced

I first decided the shape then I transformed it, made with that system if I decide to stretch it or raise it or change the shape of the lateral channels within the sketch and in a moment I solve it and the subsequent works follow the modified sketch. the other way I have to act on each side individually

the other way you can make the change you posted, but now no if not with additional adjustment functions.
but also wanting to do all the profile in a single sketch, which as I wrote can be a procedure that only in hinds turns out unsuitable, why do an extrusion and turn it into sheet instead of doing directly the sheet?
