Hi Brian,

That is interesting, but are you aware that it is not a list of features already in Blender? It's a fundraiser and wish list of some potential ideas for the future.
Whichever developer takes up that task will find pretty quickly that Booleans and Fillets are an enormously complex area and cannot be easily coded from scratch without many many man-years of effort just on those areas alone.

Yes!
But have you noted the usually small time frame in Blender between an idea and a fullfillment?
And, keep an eye on 3D Coat in that Nurbs area also.

Sometimes yes, and sometimes no.
For NURBS it is rather more the "no" case though - this is not even the first time that there has been some attempt at adding more NURBS features into Blender,
check out this discussion here from 2003 that is referring to an earlier idea and attempt at adding more NURBS functions into Blender.
It's now 2010 - is that the kind of "small time frame" that you are referring to?
There are a couple of reasons why it is not very realistic to expect to see advanced NURBS functions in Blender.
One is that NURBS booleans and trimmed surface functions are very difficult to implement, if coding them from scratch it requires someone who has a lot of experience in that particular area, not just general coding experience, and even then it requires an investment of many years of work.
Another reason though is that Blender is focused more producing animation and graphics type projects and not very much on precise accurate product design type modeling which is what NURBS is more about. So there is a kind of mismatch in general toolset between those things.

Yeah, I think I've seen that he wants to add a NURBS import feature which would be interesting! The discussion thread for that in the 3D-coat forum is here:
http://www.3d-coat.com/forum/index.php?showtopic=3052&st=0
But again - you may be getting confused - there's a big difference between importing NURBS and doing variable radius filleting modeling functions.
Just because a program implements one particular kind of NURBS feature does not mean it will suddenly have every single kind of difficult NURBS calculation included with it, which seems to be what you are assuming.

Was it just January--
Unreal--Free
Unity---Free
Bullet Physics---Free
Ptex--Free!
Ptex in 3DC now, Bullet even coming in the next version of Carrara.

Those things are pretty cool!
But what does that have to do with the topic being discussed here: variable radius NURBS fillets?

Hi Michael, variable fillets would be cool but if it represents 80 weeks of work to implement, I can easily live without them!

In my case it is not as dire as that, because the geometry library that I have licensed does have support for it.
So I do expect to be able to have these once I get a chance to design a UI for it.
The many many years effort would be for someone trying to code them up completely from scratch instead of licensing a library to do it.

Ah, in that case, it's a definitely wish list item for a "not too distant update" :P
Good news :)
