AutoCAD 2012 Offset Edge

The new Offset Edge tool, available on the Solid Editing panel, enables you to create an offset curve from a planar face or from a surface where all the edges lie on the same plane. After you select a face, the edge of the face is dynamically offset to the inside or outside based on cursor location producing a polyline or spline. During the offset operation, you can access the Corner option to specify sharp or rounded corners for the offset curve. After offsetting an edge, you can use the Presspull tool to easily add or remove the bounded area from a solid.
