Fillet Sharped edge surfaces

Hi. I want to smooth the sharp corner of the almond design on Rhino but it fails. I am using the fillet surface command and choosing top and button surfaces when it is asked. It adds a smooth edge but keeps the sharp edge as well. How can I replace the sharp edge with a smooth one?

Looks like you need to ser Trim=Yes in the command options.

It doesn’t make any difference! it keeps the soft edge separate from the geometry again. Same as before!

Hello- it’s hard to say woithout the file to look at but clearly the fillet is not finishing, for some reason, here:

I could share the file. I merged all surfaces on top and bottom and did it in separate mode as well and nothing changed. Any help is appreciated!

Hello- I see that at r= 5 the fillet does not complete on one side. The slolution for now is to take what it gives you, Split the surface with an isocurve on the Quad

and then mirror the good half over and trim with the edge curves.

Thanks @pascal . Is it possible for you to share the modified file with me? for the one you attached at the end

I figured it out @pascal ! Thanks again!
