Schwarz minimal surface

Hi there, I’m doing some research in form finding stage. I try to manipulate (extend) an “arm” of a schwarz minimal surface without changing the diameters of all circular openings.

Maybe someone might help me out on how to fix the anchor points, so I have “stable and defined” circular “arms” with similar diameters.

Thank you Quan Li, that’s very helpful.
Now I have to recap your approach a little.
