Fillet surfaces issue

Hi, I can’t fillet the edge of this 2 surfaces. Is it because it ends in point and therefore even a smallest radius will not work?
(I cut the top to try on example 2 and it works). What could we do in a situation like this?

Thanks

Make the fillet manually with FilletSrf.

Hello- you can get there by adding new handles and setting the end handle radii at each end to 0

Rhino still does not trim the fillet in, here, but it builds it correctly and you can explode the object and trim each surface back with the fillet edges.
Yes, I imagine it does not behave well here becuse the one input surface structure comes to a point.

Thank you! I have tried your way and Pascal way, but I don’t manage to trim or split. it says objects do not intersect.

When you trim, use the edge curves, not the fillet surface itself- You can DupEdge to get a curve object from the fillet edge and use that, or Ctrl-Shift click on an edge of the fillet, then , when that edge curve is seldcted, start Trim and click on the edge of the surface to trim away.

ok! yes, it makes sense! thanks!

Pascal answered in the same way I would (dup edge or subselect edge to split).
Also, at the beginning, on the top and bottom I used Pull to project original surface’s edges on the fillet to maintain the external silouhette.

Thank you both!
