Maybe you know this, if not, consider Edge Softening.
… obviously this is just a cheap trick and good only sometimes for aesthetical preview… OT.
…if you put it that way it seems Rhino started doing thing worse than in past. It’s not, but the progress in this matter is small to none.
Rhino 8 today can’t do fillets as good as other software did in 2010… and even surfacing tools are somewhat stagnant.
In my field I’m lucky I work with SubDs so the few times I need good fillets, I almost have fun doing them manually…
