Trim Curves not intersect but Z project

[ctu6]

Hi All,

I’m trying to trim a set of curves with another single curve, however, at some locations they are not intersected.

In the uploaded GH file, I also did another walk-around version by Extrude Crvs > Brep/Curve. Although it works but later on i will have x10 amount of the curves to do the same thing…
Wondering if there’s a more efficient way to do so? (Like in Rhino can trim from extend line)

Thanks.
