I made the following simple cubes in Alias. It’s not complete yet. I used Alias to fillet some of edges. Then for testing purposes, I exported it as STEP file and imported it in Rhino 6. I removed the fillet in the following corner and tried to build it in Rhino and of course with G2 continuity. I used NetworkSrf command and by adjusting tolerances and setting all 4 sides into G2 radio button, I created the manual fillet but reflection shows sharp discontinuity. Why?
