First time poster here, and first time working on a ‘complex’ model, so apologies if the grasshopper file is hard to follow (or questionable logic to achieve the result).
Effectively, I have two geometries that I am trying to Solid Difference (I believe this is the grasshopper equivalent of Boolean Difference?): in this case, I am trying to subtract the long ellipse shape from the twisting tower, in order to leave a hollow tunnel. From what I understand, the error is that the tower is not a BREP (it seems to be a group of surfaces?)
I would really appreciate some help with understanding how to get the tower to be a BREP, or whatever else I need to do in order for this operation to work,
