Hello
you already posted the same question.
You ask a question withouth giving any clue,
- reference of the work ?
- https://ifdesign.com/en/winner-ranking/project/shenzhen-cine-sky-cinema/257205
- https://decor.design/fr/cinema-nouveau-larchitecture-des-salles-de-cinema/
- Cinesky | Jonathan Leijonhufvud Architectural Photography
- what is your aim (rendering, making …)?
- What are your parameters ? Grasshopper is a parametric tool, so you need parameters and has you are in command you have to choose some of them. You also need some algorithm, this forum can help but with such a vague question it is hard to help efficiently.
I think you must read the advice given here
