View 2D Plane of 3D Graph

I have plotted several spheres and I would like to see only the circles created by those spheres at a given height along the z-axis. I have tried to udnerstand the slice fucntion, but I've been unsuccessful and I'm not certain its even the function I need to use. In short, I want to see the intersection of the spheres with the x-y plane at a given z-value. How can I do this?

If you are unable to get slice to work, you can do something like this.

[X2,Y2,Z2] = sphere(100);
X = X2 + 0.5;
Y = Y2 + 0.2;
Z = Z2*0.5 + 0.1;
surf(X,Y,Z)
hold on
surf(X2,Y2,Z2)
hold off
p = gca;
p.View = [0,90];
Zslice = 0.2;
p.ZLim = [Zslice-0.005,Zslice+0.005];
