How to cut or split a Delaunay Mesh

Hello everyone,

I wanted to know if it is possible to cut, or split a delaunay mesh ?
Basically I have list of points, which constitute my delaunay mesh. Then I want to cut or split the mesh with either plans either a closed polyline. In attachement I have put what I could do until now on grasshopper.

I tried the component Mesh | Plan section, but i can not get the differents parts of the mesh splited.
I hope it is understandable, sorry for my english :))Delaunay Mesh to split.3dm (253.2 KB)
