I had a query about trying to split, or ‘boolean’ a surface with an object created in grasshopper in order to match it to the floor shape.
I have tried baking the structure then boolean differencing the surface with the object, but the file keeps crashing, or saying the object created in rhino has open ends… and is failing at doing this simple task 
So I have gone back into the script and looking to see if there’s a way I can split the surface (shape of the floor) with the final object (space frame floor) using grasshopper. Would you know how to resolve this?
I have attached a screenshots of the problem shown in blue layer colour. As well as a copy of the GH script :).
