Trimming lines with a kangaroo generated surface

Hello to the community, as I am still a beginner I can’t find a way to connect the surface generated by the kangaroo and the volume made of lines that I want to cut out.

Indeed, I would like to trim its lines and to be able to create a shape afterwards.

And is it also possible to organize the calculation or to spread it out in certain parts in order to lighten the Grasshopper.

I would like to have some advice and help in order to understand how to create the desired geometry.

Thank you in advance for your kindness.
