How to intersect Voronoi cells with frame & cutting holes into faces

Hi folks,
I need help with two issues.
1.) I wanna intersecting this Voronoi cells with the frame segment. I tried out a few things but I don’t get it.
2.) Then I wanna cut holes into the brep faces with the Voronoi cells (the brep faces will produced with 3mm metal sheet). Later I wanna unwrap the faces to laser cut them.

May anybody can help me out with this issue, please? I attached the .gh & rhino file.
thanks a lot! :pray: :hearts:
