good evening everybody,

I came across a problem today.

-I have x amount of points

-out of this pool of points I would like to extract just the points at the perimeter

-then connect those points with a closed polyline ,creating an outline.

It is easy with the example shown but becomes tedious if you have to deal with 50000 points.

I would appreciate if someone could help me with this problem.

Thank you!!!
