Cut surface by solid.

Hello everybody! I've faced with a problem cutting surface with a multiple or even one solid. Of course i can convert surfaces to solids by offset and lofting as i did with my slabs, but is there a way to cut surfaces?

Thank you!

connect the surface to brep join, flatten the surface input so it makes one surface, then cap it.

odd, just noticed some components are icon, some are text title

right click the component and click the paint bucket icon next to the components name.

ok, I know that difference component needs two breps and it's clear with converting to the solids, but is there a way to cut surfaces by breps? for ex. my slabs...

the method is like this

using brep/brep to get intersecting curves on the surface, then trim the surface with those curves. Its hard and computer heavy on your model because you have some spheres cutting multiple surfaces and some cutting surfaces in the same place, so the data is all out of order and mismatched. I think the previous method with making solid floors then doing solid difference for this particular example of your tower is better and more computer friendly.

Because of my low knowledge of GH i was just looking for some way to increase performance, because working with solids takes twice more time than with surfaces or curves. For ex. in this def. changing the seed of spheres distribution takes up to 12 seconds on "quadcore2.64,4gbRAM". And its a so simple model. Maybe i don`t know smth. important, maybe i'm not going right?

Split surface will take even longer. It is a component I try an avoid as much as possible. Truth is GH is just slow sometime. It's doing alot of work. One thing is you could disable the solver while adjusting things. It's the lock icon in the wheel menu.
