I did something similar today here's what I did 1) Generate a list of all the distances from all the points to your test point.
2) Sort the list of distances with a sort component, but add your list of points as an optional list of values to sort as well. This will create a list of points ordered by how close they are to your test point 3) Get the first, second, third, etc.. point from the list of sorted points by index (0, 1,2 etc..) to get the first, second, third closest points to your test point. There may be a better way but this worked for me. Eric On Apr 29, 6:00 pm, Arlen <[email protected]> wrote: > Hi, > > This is my first attempt at a definition.
