Round sharp connected or disconnected interior and exterior faces to create a seamless blend between the faces or detach the blend to create new faces, defining a radius or constant width. Further define the blend cross section (rolling ball or swept profile), symmetry, control, trim, constraints, and limits.

The Face blend feature is a set of surfacing options used in situations where more control is required than a fillet. Where a fillet can be applied only between connected faces and cannot create a new surface, face blend can be applied to both connected and disconnected faces, and can create multiple face blends that can be detached from the faces on which they are applied.
