Is rhino "SrfSeam" in grasshopper?

Hello, everyone,
I want to ask
There is such a function “SrfSeam” in the Rhino panel
Is there such a function in grasshopper?
Because my current job is facing such a problem
As shown in the picture
The first circle is cut in half by the curved line
But I want to adjust that curved line in grasshopper but I do n’t know what command to use444

I’m not sure if I understood you correctly, but maybe this could help:


This is what i want to say

thanks :sweat_smile:
