Hi Brian,

> There was something about a plugin I thought for SketchUp quite recently?

For actual NURBS surface variable radius fillets? Pretty unlikely, but if you find the link please post it.

You're probably talking about some kind of sweeping technique for generating polygons from some profile curves, that's not the same thing as a fillet.


> Certainly other than ViaCad?

Yeah, it is not unusual (and in fact rather common) in NURBS based CAD programs to have it. But neither SketchUp nor Blender are NURBS based CAD programs.


> You may be interested in this about Blender Nurbs.
> (A lot more info about)

It is interesting! But please note that the tutorial you link to is all about control point manipulation of an untrimmed surface.

That does not particularly have anything to do with variable radius fillet generation.


Maybe you are confused because it refers to "NURBS" as well?

Just be aware that NURBS can sometimes refer to a just a simple surface by itself and not necessarily trims, booleans, fillets, and additional stuff like that.

As far as I know Blender does not support any of those kinds of Trimmed NURBS operations, like booleans for example. Getting those kinds of operations working is a very considerable jump in complexity from basic untrimmed surfaces.
