I have build a quadraliteral curve with another quadraliteral curve as "notches". Is there any possible way to insert vertices at the point where the vertex / point of the one hit the other curve and cut them out?

You can also achieve the desired result by extruding your mesh or curve and then simply using the node Mesh Boolean.

In this example I used a different structure than you, but the principle can remain the same:

  1. First extrude your mesh with the node Extrude or use Curve to Mesh if you still want to use curves.

  2. Then create the difference between these two meshes with the node Mesh Boolean.

  3. Since you only need the lower parts of the mesh, remove everything above the Z position $0$.

  4. Finally you can convert the resulting mesh back to a curve with the node Mesh to Curve.

enter image description here

PS: By the way, with this technique you can easily select the points along your curve where you want the notches to be instantiated and where not (Input Selection of the node Instance on Points)

  • $\begingroup$ at first, i not will not use the bool node. :-/ but when i can it return to a curve - this is realy a nic setup! thanks a lot! $\endgroup$

As far as i can see - there is actualy no possible way to bool two curves. :-/

The only way to get my result, without mesh boolean, is to draw all lines individuell... the result is this "node monster".
