I'm designing multiple turbines and when i got to fillet the blade to the hub I am not allowed to make a fillet as large as I want it.  It worked on one set of blades but doesn't seem to work on others despite that the geometry has only changed slightly and my method hasn't changed for either one.  I have a picture of a working preview of the fillet that worked and the finished model and then the error i get on the other blades when trying to fillet.
