We’ve added SubD support for Bevel command in the latest Rhino WIP.
There are several things that are still work in progress, e.g. OffsetMode=Proportional and bevel positioning in Smooth mode.
Please, test it out and share your needs and wishes so we can make it into a useful tool.
Hi @Jussi_Aaltonen
Initial testing shows KeepCreases=No not working. Creases are there, no matter the setting - unless I’m misunderstanding the option. Note the thick edges, indicating that the result has creased edges on the side of the bevel.
