Hi all - I’m pretty new to GH and wonder if I’m missing something here.
I’ve got a series of BREPs, essentially a cluster of cubes generated from previous operations. I want to subtract an extrusion from the set, so that it effectively cuts a tunnel through the mass of BREPs.
It works perfectly using Rhino’s boolean difference, and Grasshopper’s solid difference works when I bake and re-reference the BREP sets from Rhino, as shown.
However when I use the BREPs outputted from previous operations within Grasshopper, each trimmed BREP includes an attached copy of the extrusion as shown.
Am I missing something obvious? Any advice would be appreciated.
Thanks a lot,
