Fillet brep edges problem

Hi everybody, I’m trying to fillet the edges of a brep but all the attempts failed.
Any suggestions? Thank’s.

I get this error when I open your definition:


I got this in Rhino 6.

I haven’t looked at the file, but if it is your idea to fillet edges where the lofts come together in one point, then forget about it, this will also fail in Rhino. That’s also something btw to check out for yourself. If something fails in gh, first try to do in Rhino, then you get more of an idea where it fails and why.
