closing a polyline with unordered points

Hey guys, I'm trying to close a polyline which works in a "clockwork" like fashion, closing a simple polygon.Is th My points are coming from a list which is not sorted according to the connection logic. I was wondering if there is a straight forward solution for this. Perhaps it needs a loop . Thanks as always

The classic way:

1. Define a plane out of the chaotic pts (Plane Fit)

2. Define a Sphere out of the chaotic pts (Sphere Fit)

3. Intersect 1 with 2.

4. Sort chaos along curve from 3.

PS: it works ... but not in all occasions (topology wise).

It doesn;t seem to work.. I should say, my polygons are non planar and rotated in space. is ther a component or script for this? it seems like a common task but I couldn't find anyhting on the posts..

Well ... Concave hull (not convex) is another way ... but since that's internal (sorry) get the LOL sort for assured LOL results - ISO9000 certified.

PS: There's another less LOL option as well available.

May the Force (the Dark option) ... blah, blah.

best

Er ... hmm ... this is primarily a LOL thingy yielding LOL things meaning that it's only for (LOL) fun. Other cases available as well (SLOL, FOCL, DOCL etc etc).

he, he
