Split brep with brep

Hi all,

I have a small problem with splitting brep.
I have a sticks like on the attached image and I am trying to split them with a shape also imported as brep.
but for some reason it doesn’t fully work and I’m not sure what I’m doing wrong.


It is nos easy to answer without file! Surely a problem with core rhino function that fails on that. Did you try to bake and do it in Rhino ?
Change tolerances and recompute (there is a menu to do that in GH) it sometimes help.
