Issues with Fillet command for Curves

Hi! I just recently updated my rhino license, and I have noticed a problem with filleting curves. Please see the attached screen shots for reference. When I fillet a curve, it sometimes changes the angle or construction of my original geometry into unwanted results. It takes a few tries to get the result I want, and each time I fillet, it’s a different result. I did not have this problem with the previous version of Rhino for Mac. Has anyone else had this issue since the Mac update? Does it have something to do with tolerances?


Fillet not even at all

Perfect square before fillet

Hi Bo,

I think you found the solution to be related to the unit tolerance for the file as discussed in the tolerance settings thread linked here. If you still have an issue, please post a 3dm file and I’ll try to help more.
