I’m back using Rhino after a few months and I may have forgotten something vital here. I’m trying to fillet all the edges on the attached polysurface with a radius of 0.24. The central opening just will not fillet. I’ve tried Fillet Surface and Fillet Edge. I’ve rebuilt the curves that I extruded to get the surface. No luck.
Rhino 6, SR18
