Only Outline of a 3D Plot Needed

I have got the following 2D view of a 3D Plot. Is it possible to just get a plot of the outer line of this curve and eliminate all the inner colors and lines? I just want the outer shape. Thanks in advance.

You have to decide at what location of (x,y) you want the z values (pressure in your case). Eg:

[X,Y,Z] = peaks(26);

figure
surf(X,Y,Z);
xlabel('x')
ylabel('y')
zlabel('z')

x = unique(X) ;
y = unique(Y) ;
z = Z(13,:) ;
figure
plot(y,z,'*-k')

This will not work in my case since I have generated a surface plot using the curve fitting tool. The image I have posted here is after surface fitting. Any other alternative please?

Not a deal..even after surface fitting, you have data in hand. It can be extracted.
