Modeling trim (or chamfer/scallop?) 45deg 3d chunk cutout?

[stephen.hayne]

Can anyone advise how to model a simple 45deg triangle 3d cutout?  I'm trying to clear an area at the base intersection of two rectangles - here is the basic design image, the actual piece I am trying to replicate (I've circled the spot), and the current model...

I'm still REALLY new to all this.  Just learning as I go.

After doing some more reading, I thought maybe I could "trim" with a sphere, but can't get that to work yet...

Extrude > Cut will do it.

Sketch a line  at 45 degrees to the base of the fillet, 

Then plane on Angle on that line, (90 deg)

Sketch the cut profile to suit on the second sketch.

Wow - both of you are awesome.  Thank you for the guidance!  I will try this and report back.
