create fixed size of openings diagrid panels attractor line

Hi!

I divided a surface into diagrids. The openings of the diagrids are depending on the distance from the attractor line. Now I want to divide the openings in 6 different sizes, so it is easier to build it. So that the size of the openings are fixed, from small to big in 6 different sizes? So you have six different panels with openings in it, and these can be placed dependent on the attractor line, from big to small openings.

Thanks in advance!
