It is incredible that a simple aspect of a basic path can be completely ignored !
I don't get it... how is it EVER helpful to encounter a sudden gob of material at the apex of an internal corner when finishing?
Or for that matter, to find any extra material any where when on a finish path ?
That makes no sense! at best it causes chatter.
sometimes the engineers need the sharp corners, so I pick it out in a different setup, other times the radius is irrelevant so I can leave it.
