Smooth Region Boundary

‘Smooth Region Boundaries’ is used to smooth the transition between different regions in a design. The top slider is the ‘Max Allowable slope’. It sets the steepest allowable slope in the transition around the region lines. The bottom slider is ‘Distance From Region line’. This sets how far away from the region line blending can occur. Both values can be set manually by typing a value into the spaces available underneath the sliders.
