MATLAB: Interpolate surface between 3D lines

3d linesinterpolateMATLABsurface

Hi all,
i have several 3D lines and i want to use them to create a surface between them.
In the image above you can see two of those lines as an example. The data used for those lines is in the attachment. Below you see the code i tried to use to create a surface between these two lines.
Unfortunately, it also created a surface between each of the lines itself.
Is there a way to create a surface just for the area between the two lines?
Thanks a lot !
y = [Data1(:,1); Data2(:,1)];
x = [Data1(:,2); Data2(:,2)];
z = [Data1(:,3); Data2(:,3)];
figure;
rangeX = -1500:10:0;
rangeY = 0:0.1:20;
[X,Y] = meshgrid(rangeX,rangeY);
Z=griddata(x,y,z,X,Y,'cubic'); 
surf(X,Y,Z)
hold on;
plot3(Data1(:,2),Data1(:,1),Data1(:,3),'LineWidth',2);
plot3(Data2(:,2),Data2(:,1),Data2(:,3),'LineWidth',2);
grid on

If I understood what you are looking for then I would recommend trying 'fit' function. I think it would work
