Hi!

I've got 3 curves and I want to cut all curves from the first curve (in the future I'll have more than 2 curves).

They're planar. The problem is that the first curvesect node works, but the second not (file attached).
Am I making something wrong or this is kind of error ?

Thank you

They are both planer but not in the same plane.

Have a look at the file, it's note exactly procedural but I am sure you can fix that with an expression.
