Hi James, Yes, I think that it is possible to make irregular flat quads on a sphere. Manipulation of the point grid with something like 'SoftMove' and then using pullback or project to get the points on the sphere again might work for you. The rows of panels will need to stay linear however if they must remain flat. As soon as you have a twisting grid on a spherical surface the panels will no longer be flat when made with four sides. If you use triangular shaped panels and choose flat faces only, you can have a twisting grid while maintaining flatness. There is also a command called 'ptPanelRandomPoints' that can be used, although these will always be three sided. One last approach would be to use Grasshopper.

But that's a different topic. Thanks for the feedback.

Hi Muthahar, Sorry for the delay in responding. I've been traveling. If you could send me a file that shows what you have so far it would help me understand more. I think the main thing to keep in mind is that the shape of the surface being panelized will often determine the size of the panels and there flatness (Think of a sphere). It is possible to make all flat uniform panels in PT or GH but the results may not be close enough to the actual shape of your surface. PT has options for flat panels only and if the spacing of the point grid is uniform, the panels will be as well. In your case, the eye shaped surface may work best with triangular shaped panels which will also be flat by default.
