This video will demonstrate the PolyBevel tool and the number of option controls that exist inside. You can apply PolyBevel on either an entire geometry or on a grouped selection that has been made previously (you can just select the geometry you want, hit TAB key and type Group to assign them into a grouped selection). Once that is done, it's just a matter of tweaking Offset (Fixed Distance/Fixed Width), Fillet Shape (Solid/Crease/Chamfer/Round/Profile), number of Divisions and Vertex Splitting (Allow Vertex Splits/Split Miterable Joints/Split over All Incident Edges). Keep in mind that based on what your selections are (for example, face loop vs edge loop), you will get different results – with the same settings. So don't be shy to try out all those options!
