Fillet edge weirdness

Widget.3dm (310.8 KB)

v6 trial. Trying to fillet the inner edge of this using blend option (0.1 or 0.08) and it seems generate a surface across the hole!

Hi @Tone,

Try using “FilletSurface” command instead, worked for me perfectly with 0.08:


The “surface” is actually a render (display) mesh problem, not a NURBS surface. Very strange.

Hello - I see this - it seems to be the existing fillet at the outer edge that goes wonky - still digging…
You can fix it by ExtractSrf on that outer/top fillet surface and UntrimBorder
