Trim lines when crossing brep

Grasshopper

Hello! I need some help, I have lines going straight down to the x-y plane and I need all the lines that intersect a brep to stop there and the other ones to keep how they are. Is this possible? Thank you in advance.

try the function ‘BCX’ (brep curve intersection), output are intersection points. you could choose to redraw your intersected lines from starting point to intersection point.

this is a quick & dirty way to seperate intersecting and non-intersecting curves

This worked perfectly using by breps in the obstacles instead of the starting surfaces, thank you very much.
