Intersection with multiple Breps

Hello I have following problem:

I want to intersect multiple Breps with Lines, but there is only on the Breps selected.

(see first picture)

By Grafting the  "B" imput of the Brep | Line Component i could solve that problem, but now geometry behind the Lines also get cut.

(see second picture)


--> How can i intersect multiple Breps without influencing what ist behind the line?

Hopfully you can help me.

Regards, Robert

Use the Project Curve component.

Hello, sorry for the late answer.

It worked with Project Curve, thank you very much for that. But it also projects the curve on the Breps when they do not have any intersection. So i only want an intersection when they are really intersecting. Is there a way to fix that?

New problem appeared:

Is there any possibility to show the intersection-points just of the first Brep the line intersects? Or something like that:

overall there are 50 lines

30 Lines have at least one intersection

20 have no intersections

Hopefully someone can help me!

Robert
