I was rebuilding the attached file in Rhino 6 that had works fine in Rhino 5 and I am getting weird result.
I am trying to do edgefillet’a between the circular area and the extension at 0.125 rolling ball.One of them comes out and the other does not, even though the shape is symmetrical. in fact, when I rebuild the polysrf, the side that works and does not work can alternate.
I can do a chained Distance Between Rails fillet along this edge at 0.125 but on Rhino 6 it does not work.
