Hi Davide - how are you setting the handles? Here, if I splitEdge at the ends where the radius drops to zero, it looks like what I think you want… Handles added at the edge between the vertical surfaces. and end handles set to zero.
Thanks Pascal.
Why the fillet / blend edge extends incorrectly (yellow curve)?
I think it would be more correct that he had a path equal to the green curve, G1 or G2.
exact.
Give the possibility to perform the fitting or as above (where there is written OK), or extend the fitting, beyond the curved edge, but following the green curve.
Hi Davide - It seems to me that if you want the latter, you can force it in the way that I described - otherwise there would need to be more UI to set where the end will be. My thought is that the hard end (Your ‘OK’) should be the correct behavior if possible and to make it extend, you can split the edge as I mentioned.
Certainly, currently Rhino v5 implements the filet / blend edge of the red edge, extends it further, but it is extended following the yellow curve, not the green one (more correct).
They are two different possibilities, both valid.
I would take a look at solutions of this type, in which fillet / blend edge can not be generated.
Where there are discontinuities Rhino struggles a lot to do the fillet … fillet_blend edge failed.3dm (824.9 KB)
