If you want to spawn an object on Point instance one, on a new event line:
Pick nth instance: and choose Point, then 1.
Then have Point spawn another object "Line" at Point.x/Point.y
To point the newly created line at the next instance, align "Line" to Point(2).X/Point(2).Y <-- (it's actually typed this way) Check the UID/IID example for a more detailed explanation! Good luck!
