im using aspire 4.0 . i can t figure out how to get a clean edge on my two rail sweep on the inner circle. I assume that the ball end bits center starts and stops at each rail. the center of the circle is cut out on the inside with a straight bit but i still get that vertical visual in rendering. file is to big to send so i took a screen shot . red arrow is what i'm trying to describe. thanks in advance for your time in this.
