Trimming a parametric truss with a curve


I’m a beginner in using grasshopper and I have a problem with how to trim a truss with a curve to modify its shape. Picture below

I don’t really seem to get the desired results with anything that I’ve tried and I’m running out of ideas. I would appreciate if someone could give me some tips. I’ve attached the gh file to the post.

Thanks in advance
