Floors coincident with points of diagrid

Hi, I’m modeling a building with an elliptical form and it has a diagrid. I need to make every floor aligned with the points of the diagrid without changing the number of suddivision in V direction. I already made floors so I thought to move the floors that don’t coincide (one for two) or create new floors as interpolation of points but I don’t know how to create a list of points with same z.
