Culling Sun Vectors that intersect with context brep

[Lizzie_Higham]

Hello! I’ve been trying to cull sun vectors from “LB Sunpath” to show only the curves that don’t intersect with given context. I have converted the vectors into curves and then have tried to use “Curve | Breps” to find the curves that intersect with the breps, but the curve output of this shows an ‘empty curve parameter’. I need help figuring out how to get a true/false pattern for the intersection to then use cull pattern, please help!
Thank you!

You didn’t internalize your Brep ‘CONTEXT’ geometry.

Apologies! Here I’ve attached a document with everything internalised,

Sorry Joseph! I uploaded the wrong file, I’ve triple checked now, this is the right one!
