Challenge: I would like to construct a grid of rectangles, with different step sizes. What do I have: List A: a list of numbers, representing the step size to the next grid line in X-direction List B: a list of numbers, representing the step size to the next grid line in Y-direction I do know t…

This looks idiotic but Grasshopper is quirky that way. It’s a VERY IMPORTANT DETAIL… I had to round off the centroids (I used two decimal places) to get Sort Points to behave nicely. See purple groups. :man_facepalming: [rectangular_grid_2020Apr3b] rectangular_grid_2020Apr3b.gh (30.6 KB)

Hi Joseph, Thank you very much :slight_smile: It does the trick ánd with very few commands :slight_smile: However, there is still 1 challenge to go. I noticed, that the surfaces items are not sorted in a ‘logic’ way, but more in a random way present in the list (possibly it has to do with the sp…

Sorting geometry is a common problem, there are many tricks to accomplish it. See white group for one: [rectangular_grid_2020Apr3a] rectangular_grid_2020Apr3a.gh (13.4 KB)

Ahh thank you once again! It works perfectly for the X,Y plane. The only thing I must admit, I don’t fully understand the part (deconstruct point -->rearrange x,y,z --> point --> sort point). Because when I try to do the same for a surface in the XZ plane, or XY itdoesnot seem to work. Yes, I did…
