Hi Marc, well it kind of depends on what you mean by "a lot" ... :)

It's probably a couple of days worth of focused work, but that kind of puts it into a category of stuff that becomes more difficult to schedule.

It's something that's simple if you only have a fillet between 2 line segments of course, but with 2 arbitrary wiggly curves rather than just lines it's a much different scenario to deal with.

It's a good idea though and I'd like to work on it at some point, it's just difficult to know when.
