I have a half hood or I have folds on the lower and upper part, I have made the parameterization through equations the problem and when I move the length or the width or the inclination, I have all my folds from the sheet metal function bend on edge which are not good because an angle value and impose in this function, It is impossible to add vertical or horizontal relationships, so that the top of the hood remains
