Use Show[{top, bot}, PlotRange -> All] Alternatively, use Plot3D[{Sqrt[1 - (x^2 + y^2)], -Sqrt[1 - (x^2 + y^2)]}, {x, -1, 1}, {y, -1, 1}] Or more compactly, Plot3D[{1, -1} Sqrt[1 - (x^2 + y^2)], {x, -1, 1}, {y, -1, 1}] Bob Hanlon ---- Narasimham <mathma18 at hotmail.com> wrote: > 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 >
