Hi all,
does someone else also have difficulty with the Curve Intersection component? In some cases, it simply does not give the results.
I tried to lower model tolerances, but nothing changes

Thanks!
Graft one of the inputs.

the one you show is a data tree problem
you are trying to find intersection between curve 0 and line 0, which obviously do not intersect 
same for curve 1 and line 1, curve 2 and line 2… and so on
you can either graft CCX input A or B, depending on how you want output data to be organized
grafting CCX input A will give you a tree like:
{curve index; line index} (intersection points)
grafting CCX input B will give you a tree like:
{line index; curve index} (intersection points)

As @inno pointed out - intersections work properly (no need to graft) if intersecting curves share the same index.
Sorry guys,
somehow I made the wrong selection when creating the example file. Here is a new file where data trees are matching. Please take a look at the curves on the left side

Or you could sort the curves. Wait, moving the goal posts?

I found the issue, they were not projected correctly

Thank you inno,
I had to also check is all curves are planar
