Sort Point Data by X Coordinate Then Y Coordinate

[austin.guter]

I am trying to organize point lists based on x coordinates then y coordinates and was running into some trouble.

An example probably shows this clearly (excuse my poor example i realized i sorted by y then x in my picture, too lazy to fix, hopefully the point is clear)

Currently I can organize my data by x, but it fails to organize by y afterwards as I had anticipated.
Is there an easy way to do this?

My mind goes to chopping the list if the x value changes from one value to the next and then organizing based on y values of the sublists and then splicing the list back together.

Any easier ways come to mind?

Thanks!

@austin.guter have you searched this forum ?

List sort by key by z then by y then by x location

Hmm, I tried your script, but it’s still not sorting the X at the end for some reason. I flipped the itemgetter(1,2,3) to itemgetter(3,2,1) since I want to sort by Z first and X last. It sorted by Z then by Y but failed to sort by X, as you can see in the screenshot below. What do you think is the reason? [sort%20by%20z%20and%20group%20then%20y%20then%20x4]

Ooh, fine

Group Points based on X & Y coordinates

Hi all, I’m trying to group the points based on theier X & Y. I’m using Group by Key values but can do only x or Y. How can we put both conditions together? Group by function maybe?? The intent behind this grouping is, for elements it returns points on top and bottom edges of any element. By grouping this, and giving a condition to filter points with Z of point > Z of other point in the same group, whoch will give two list one for all bottom points and other for all top points. Please take a …

Could you sort by X, apply a list chop to the length of the row count, then apply a List Map/Sort to the X sub-lists by Y?
