If possible, add this command to the subd and mesh!!
To be able to perform twist, division and so on. Thanks
There’s a request on file for making edge loops circular. I think that’s related to what you’re after and I added your request there https://mcneel.myjetbrains.com/youtrack/issue/RH-55054
The other subdivision and twist things you’ve shown are possible now but not in the form of an editable modifier. That would be a major change to how Rhino currently works. You can bring in meshes as FBX or OBJ though from Maya to create your SubD surface if you prefer how the modeling works there.
Yes that’s right
