I have drawn a part that has a curve (1 piece of paper that will be stick to a curved surface - see attached part). I would like to know how can we unfold the part so we are able to have the flatten version of the part. I have tried using ''converting to sheet metal'', but it seems that it only works for linear surface. Moreover, I have tried to use the sweep function with the sheet metal function, but the sweep function only allows lines and radius, not curved lines. Anybody has a solution for that?
