Hello Narasimham, The problem is that Show uses the Plot settings of the first image. You will have to specify that you want to display the full plot range: 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,PlotRange] That does the trick!

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 ANarasimham
