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 look at the picture. Thanks!
