Man, this baffles me...
I'm back using FreeCAD after 10 years and I got really frustrated to see the fillet/chamfers still not working properly...
It crashes almost everytime if you need to make something a little more complex than a simple cube.
It seems this is one of the most common topics about it since forever. And here in this forum as well.
What is the point of adding new features if the basic things don't work, it there are bugs dating back to 2000's and still open ?
Shame on you OpenCascade.
I wish FreeCAD wasn't held hostage to this """wonderful""" piece of software.
