Hello - there is not such a tool in Rhino - It might be possible to hack something that would work in a script, in fact I might have done something in the past, I’ll look around and see if there is anything worthwhile.
In surface modeling from an aesthetics point of view you try to avoid any straight surfaces, as i also model in alias, this feature is being used all the time and i miss it alot in rhino, many times out of lazyness i end up not crowning my surfaces and it just makes some parts look dull.
also, when youre working with alot of surfaces, you dont want to do it all manually, would be nice if its available as a preset.
My goal is to be able to move the curves around and simply not have to think about the surface, since that will always automatically have a nice curvature, regardless of what you’re doing to the curves…
Anyway, this is one of the earliest threads I made when I started out with Rhino I think, and since then I’ve discovered that all of these kinds of requests are kind of moot until history becomes more robust. Until then, there can be no fast design iteration in Rhino.
