Hi Narasimham,
if you plot a surface of revolution, the curve in the x-z plane is
independent of the rotation angle. However, your curve does depend on
this angle and therefore, your surface is no more a surface of
revolution. That this works at all is an undocumented feature of
SurfaceOfRevolution.
