Plots are objects that can be added, so you can first create the plot of your function:

sage: F = plot3d(lambda x,y: x^2+y^2, [-2,2], [-2,2])


Then the plot of the plane $z=1$

sage: P = implicit_plot3d(lambda x,y,z: z-1, (-2,2), (-2,2), (-2,2))


Then you can add them on a common plot:

sage: F+P
