How to split a curve by a point?

And how in GH to cut a certain curve with a selected point?

Get the t parameter of the curve for example with the curve closest point than feed it into the shatter component. After that use the list item to stay with the part of the curve you need.

Well, but a special tool would not hurt.

If you want a shorter way, Pufferfish has a Trim Curve with Points component.

is there any way to split a curve with 2 points or more on it with this method?
I have a circle and it does 2 intersection points with 2 different surfaces, and I want to split the circle curve with these points, but when I want to extract the T parameter from “surface | Curve split component”, it doesn’t work properly on the shatter component. I attached my file below and I would be very grateful if Somebody can solve this issue, thanks.Normal Vector.gh (16.4 KB)

Sure, if you reparametrize in the intersection component do it for shatter too.
