To rotate the axis of the cylinder, you can simply change the order of X, Y, and Z. To change the axis of rotation of your curve, you have to calculate the surface. @Ngan Shan: Ok, I understand now. I've added another way to change the axis of rotation. That's a brilliant way of rotating it Jonas. The vector tangent to the surface in the x-directions is rx = (1,0, ∂z ∂x). The vector tangent to the surface in the y-direction is ry = (0,1, ∂z ∂y). The area of the tangent plane is then the area of the plane with sides of length δx and δy and direction given by the two tangent vectors.
