Hi All What is the cause of the problem? Fillet edges-2.3dm (4.7 MB)

Hello-- Rhino intersects the fillets at the sharp corners, presumably to keep the corner sharp as on the input. [image] Obviously that does not play well here since the extended fiiets do not fully intersect - a linear extension might work better but the extensions would need too be very long. […

workarround 1 fast and dirty do a very tiny fillet arround 10x document tolerance do the desired fillet. depend on the data usage - this should be fine for 99% of the cases [Screenshot 2021-10-15 at 19.31.52] workarround 2 more work but precise use _filletSrf (extend = no ) build a _revolve …

@pascal inside corners only have a circular solution for a special case: the edge has to be rectangular to a planar surface. as soon as we go freeform it s getting complicated [Screenshot 2021-10-15 at 19.44.47] [Screenshot 2021-10-15 at 19.45.56] the red (initial edge) blue and cyan curve …

Sure, I don’t thinik it needs to have a circular outer rail - but I’ll leave that to the developer. -Pascal

nice to see that one special case finally made it to be found by filletEdge. great (at the left, 4 surfaces meet at one point at the edge to fillet, a small section is needed - blue in my screenshot) thanks for this (Rh7 update ?) but the other case still is not found by _filletEdge (middle) i…

[image] Tom_P: if a surface is touched by the fillet, but is not part of the edge _filletEdge fails. Yep - this is behind probably a large majority of failure cases. -Pascal

[image] Tom_P: 4 surfaces meet at one point at the edge to fillet, a small section is needed This is interesting to me, cause I have a client that has lots of geometry like that, which is a bit more complicated in shape – I’ll try sharing some samples later. [image] Tom_P: if a surface i…
