Boolean in/out of grasshopper

Hi so i recently made this aggregation that i want to hollow out, because its made from a set of lines i thought that i might be able to pipe out the same lines with a relatively similar radius and boolean difference it from one another after its baked, although this did not work. i tried to incorporate the boolean action into the script except the ‘solid difference’ component only uses breps (the aggregation is a mesh (made with Dendro)) Does anyone one have any other ideas on how this could work?
Any help would be much appreciated :slight_smile:
