I'm not good enough with MoI yet to emulate that effect, but within the ViaCAD Blend tool (Fillet tool in MoI), there is a Setback option that seems to give a similar result to Frenchy's example shot.

Is this available in MoI's geometry library?

Here's a sample file with several blocks to show the effect - the one closest to the origin has no Setback applied.
