I think you're going to have to do some maths or look up on google for some
corner rounding algorithms.  In my CAD package, it seems to make two
surfaces when making a corner round.  One is joining the largest and
smallest radii edges and looks to be just a torus with minor radius equal to
that of the smallest radii edge round.  Then the other section is touching
the two largest rounds and the torus.  Don't know what shape this is.

Hope this helps.
