Column numbering

Hi all,
I am trying to number the columns Left to right and top to bottom. But I would like to have the same column number based on the x, y location, as shown in the below image. I am using a script that I downloaded from this forum and trying to modify. But it is not working as desired. Any suggestions?
Col Numbering family instances sort YX.dyn (53.7 KB)

Hello,
Here is a possibility

The next challenge is auto renumber when some column is deleted or added :slight_smile:

Mr. Daan was a good teacher Create a ranking of points according to an order - #2 by Daan
(in case of addition and / or deletion by floor, it may become complicated in this case with identical numbering between floors)

Thanks @christian.stan. I appreciate if there are any suggestions @Daan?
