Please, add mesh boolean components to Grasshopper (like those in Rhino)
They would be also useful for Subds (with “mesh from subd”), (since there is Subd>Nurbs(Brep) continuity problems now)
In Grasshopper it is called Fuse for subD. See Surface > SubD panel.
This way it doesnt makes sharp edges where they supposed to be, i think its because Subd fuse is a little different thing by concept…:
left=Subd Fuse done in Gh (extracted control mesh), right= mesh boolean done in Rhino
