Yup, that's what I was thinking - that would again be similar to how Loft works currently when lofting between 2 circles. Points are displayed at the seam locations where you can drag them to update them.

So that would make sense for Blend adjusting as well.

Still not sure about automatic trimming though.

I was thinking about this and it could be cool to have these interactive points in 2d fillet also.

Unfortunately that's probably pretty difficult - curve fillet currently works by calculating the result from 2 curves and a radius value. Trying to drag one point to manipulate the curve fillet would probably involve some kind of reverse calculation from that which would involve writing a completely new solver.

Maybe a center radius point that could be draggable?

The vector scribe plugin for illustrator does something like this:

Hi Marc,

Right, but that's the one that requires a different solver.

Instead of solving the problem "find the points on the 2 curves to make a fillet arc of the given radius", it's more like "find the points on the 2 curves to make a fillet arc with the center closest to the given center point, with radius being calculated".

It's a different problem to solve and would require a different solver mechanism to be written to calculate it - that's certainly possible but it's a fair amount of work to do it. So that could be possible in the future.

Oh, I think I understand, but then again I have a bad cold. :-)

I guess It's a kind of mechanism that looks simple but takes a lot of work to implement.

Thanks,

Marc

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.

It looks to me more like a slider for the radius of the fillet.
