Hello,

Is surfc what you want? Or one of the numerous contour functions?

Or perhaps
[x y z] = peaks(50);
hs = surf(x,y,z); hold on
hs.EdgeAlpha = 0.5;
[~,hc] = contour3(x,y,z);
hc.LineWidth = 5;
Note that this is a scenario where two objects are dependent on the same colormap. Utilizing different colormaps for both the surf and contour requires extra work.
