Menu: Edit / Trim/Extend / Cut Edge
Cuts a portion off of the edge of a solid (cham- fering the edge) and replaces the edge with a flat face at a specified depth.

In the Radius field, enter the depth - the distance from the edge along the two surfaces that form the edge - to the flat surface.
Set a point on the edge. The edge is chamfered to
the specified depth, or radius.
