Remove Surface outside perimeter area

[Teddells]

Hi I am new to grasshopper and maybe there is a more simple way to do the same thing.
I am trying to create a ripple frit pattern and want to ask how can I remove surface that is outside the perimeter.

something like this but the ripples is a surface not just curves

Thank you for your time.

maybe try split brep? or split surface?

You are looking for Trim with Region:

Thanks @Volker_Rakow this is what I am looking for. Meanwhile I am wondering if there is a way using those curves to create surface. I tried to get the boarder lines that cut the circle but not quite sure how can I join them together and create surfaces.

@Zahraa_Tanana I also tried the surface split and remove surface that is outside the region. This is the closest to what I am looking for, but for some reason some surface didn’t split.

Thanks in advance.

You just want the rings? The area between original and offset curve?

[Teddells]

Yes, I want the ring / surface not curves. Sorry for not explaining well.
