Geometry split failing

Packages
1

Can someone please explain how the geometry split node works. I have a simple loft that I want to split.

  • If I try and split it with a plane I create a new surface, not split the original surface.
  • If I try and split it with curves it fails all together.
What type of 'tool' input does this node require to work?

Thanks

Try using a tool that is not in the same plane as the geometry.[/caption]
