Why is the following plot, bot, (with - Sqrt) not Shown along with top? Why is it treated only as a plot skeleton, so no combining is possible? bot = Plot3D[-Sqrt[1 - (x^2 + y^2) ] , {x, -1, 1}, {y, -1, 1}] top = Plot3D[+Sqrt[1 - (x^2 + y^2) ] , {x, -1, 1}, {y, -1, 1}] Show[top, bot] TIA Narasimham
