Hi, The following plot is not really nice, but this should about do what I guess you want: f[x_, y_] /; (x^2 + y^2 < 1) := x^2 + y^2; f[x_, y_] /; (x^2 + y^2 > 1) := 2 Plot3D[f[x, y], {x, -1.2, 1.2}, {y, -1.2, 1.2}, PlotPoints -> 50] See Options of Plot3D, or the documentation on ContourPlot and other routines to get a plot that looks better than this...
