First of all, thank you David. Substantially, I've solved the problem. But now I've still a perplexity: please, look at the algorithm in this link: is that the shorter way to obtain the grid that I want? Here I've done a cross reference on the F(X) component and then I've managed the result with a Z vector to translate the grid of X Y planar points and create my grid.
