Hi Will, just as a note - normally in CAD a bevel like this:



Is produced by doing a chamfer that cuts it away from a larger piece, like so:



Here's showing the original box in wireframe to help illustrate:




Rather than starting with the small piece and having it pop outwards from it like you would do in a polygon modeling program.


But probably in the future the Inset command could allow for that kind of "outwards growing" bevel as an alternate way.
