Hello all!

This is probably an extremely basic question, but I just can’t seem to figure it out. I have a model of many curves (a simplified version shown here);

One curve is then randomly selected.

I then find the intersection points between that one curve and all the other curves.

This gives me a tree with some branches containing points, others not (because they don’t intersect).

I need to then identify / select these curves that have intersected (i.e. branches in the tree that contain points). In other words, I need to use the Branch Indices of the (cleaned) data tree as indices for the original list of curves.

For the life of me, I just can’t figure it out, surely there is a way to just use these Branch numbers as integers and then use “List item”?

I know member index / item index would work but this seems really slow and inefficient.

Thanks in advanced guys!
