nonlinear edges in insert folds

[Alerm]

hello to all
I'm taking a little confidence with the plates and I'm having a problem.
I should insert folds into the edges of the cone in the figure
I used the loft function for the cone,after emptying,and then an extruded cut to create the edge
But if I click the edge in the insert bends tells me that the edge is not linear
if I do the same using pero extrusion in revolution instead of loft to create the solid cone then again empty and cut extruded accepts me edge
How come?
Thank you.

to create sheet metal parts is always better to use the functions of the sheet label! for this I recommend you to do 2 open sketches where there are a circle each open of 0.1mm and then the function "loft sheet".

I am new and as you are discovering the sheet functions, I do not know if you have already solved your problem but I have seen that no one has sent you a drawing already made with the sheet functions, I in order to be useful to you or to maybe the next one that will fall into your same problem first insert a cylinder created with the sheet functions and according to a flat sheet that with various bendings has been transformed into a cylinder.
