The mode of creating chamfers by offsets normal to faces can be called in the Edge Blend command using the Chamfer (Offsets) button located in the upper part of the parameters window.
A chamfer can be constructed along a selected set of edges. A chamfer can be defined by two offsets from the adjacent faces. The algorithm for constructing a chamfer by offsets is similar to rounding algorithm with variable elliptical radius and is illustrated in the following figures:
