how to draw lines between each pair of points for a group of points

may I ask how to draw lines between each pair of points for a group of points?

Suppose I have 10 random points, the total number of lines between each point pair should be (10+1)*10/2 = 55

Thanks!

(correction: the number of lines between each pair of points for N number of points is: N*(N-1)/2)

In this case, "Cull duplicatePt" method is not gonna work.

Try Kangaroo "Remove duplicate lines".

Treesloth also has a List Compare component that lets you output unique pairs of items from a list.

Thank you very much, Kim!

I wonder why the interconnectlines component is not available in the latest Kangaroo 2.0 ... which provide a quite useful function.

Thank you very much, David!

However, when i drag and drop the treesloth_v0.1.gha onto GH canvas, the component group is not shown.

Can you kindly advise if I missed anything in terms of installation of treesloth?

Thank you again!

Use this one! All of the Treesloth components are located under the sets tab...I meant for them to be a bit invisible, simply integrated in with the other DataTree management tools.

Here's also a link to some of the features: http://www.bespokegeometry.com/2015/07/07/treesloth/

Also, if you right-click on the List Compare you can toggle between full comparison and unique pairs. If you choose unique pairs of points, you won't have to remove any duplicates.
