I have attached my code.

Hi Vishal,
You can use the plot3 function to add cut line to your plot. The following Is an example, replace the second figure with the following code to see the cutlines.
%% Use you code upto end of figure 1 then add the following instead of your code
figure(2);
colormap(jet)
ax = gca;
surf(ax,XX,YY,VTHETA)
shading interp
pbaspect([(max(max(r))-min(min(r))) L_const 1])
colorbar('location','EastOutside');
title('Circumferential Velocity (v_\theta) (m/sec)');
caxis([0 0.4]);
view(0,90)
% Adding the Cut Lines
hold(ax,'on')
plot3(ax,[0.004,0.006],[0.00187,0.00150],[1,1],'k','LineWidth',3);
plot3(ax,[0.008,0.011],[0.01387,0.01350],[1,1],'k','LineWidth',3);
hold(ax,'off')
% End of Cut lines

Use interpolation (interp2) to get value of the line
