Mesh smooth with threshold?

hey all!

is there a command in rhino that lest one smooth a mesh only where adjacent faces have an angle bigger than a certain value? I have this mesh that is part organic and part ortho and i want to keep the 90 degree edges but smooth the rest.

Thanks!

Did you tried _weld? There you can set an angle limit. Maybe it’s useful to _unweld before, to get a defined state.

the unweld is actually the one that works, thanks for the tip!
