Try MoveUVN on the control points after a three segment Bevel on the edge loop like this…
If you don’t like the offset edges you get with Bevel, try SubDExpandEdges instead for that part.
That’s what I mean, let this_ Bevel+_ ExtrudeSubD
Or maybe_ Bevel+_ Moveuvn becomes a combined instruction function, do not separate
At present, it is not impossible, but inefficient. It takes too much time to achieve such a result. It should be considered to refer to the combination of the functions of its two instructions
I think what’s needed here is a new command to move multiple SubD faces in their respective normal directions. I filed https://mcneel.myjetbrains.com/youtrack/issue/RH-66910 for future reference. This way Bevel or SubDExpandEdges or simply selecting SubD faces could happen before it.
