Solid difference

Hi, i've been doing a project in grasshopper which involves these plates that are stacked, and i want to subtract spheres out of those plates. When i do a solid difference in grasshopper, it cuts the spheres into the plates, but keeps the edges of the plates intact. I would want the spheres to cut the edges of the plate too. Can anyone help?

I am attaching the rhino and grasshopper files here . Thanks a lot!

Hi Rain, since your plates are surfaces, not solids, the solid difference won't work. Also, you don't need spheres, just circles will suffice. Then you can use Region Difference:

Alternatively, You cant use solid difference. Why? because a surface is not a solid. Instead use trim solid. Also, your lists must match structure so gh knows which surface to trim with which sphere. So graft the input for the surfaces.
