Getting the longest of 3 lines..

Hi Everybody..

I'm stucked in0 a problem that I believe it should be easy to solve. I've just simplfied it in a Rhino and a grashopper file. The proble is this:

I have a drawing with a some points (i. e. 5) and circles (i. e. 3). I find the closest points from the given point to the circles and I draw the lines between those (so I hace 15 points, 3 for each point). What I need now is to Grasshopper to select the longest (or the shortest) of each three lines.

Any sugestions..

(attahfed you'll see the Rhino file)

Thanks a lot fellows. Any help I'll apprreciate a lot.

Curves (Your lines)
Length
Sort List (Attach your lines to grip "A")
Reverse list (to get the longest first instead of last)
List Item (Get the first item, "i" set to "0")
Resulting curve is the longest

I hope this helps.

Thanks a lot Marten.. Really clever.. (And I need to keep practicing). I didn't know to use that "syncrhonous element" in sorting a list. While I was trying to solve the problem by myself I found another problem. I'll post it as another discussion. I'll be thankful again If you can have a look to it.

In fact you don't need Reverse, if you set the W input of the List Item to true (should be the default in new versions of GH), then the [i] index can be -1 and you'll automatically select the last item in a list.
