I am trying to mark walls by their X and Y position in the project. Some walls are in the same XY position, but different elevation - they need to have the same mark.
So I get a list with sublists for X point
and a list with sublists for Y point
How do I assign same mark if both XY sublists at specific index are the same in the list?
