rounding, not beveled, corners

I want to change an inside corner into a radius. any help on this would be humbly and greatly appreciated.

Best thing to do is post some pics of what your working on.
That way we can help you figure out what to do.

sorry it took so long to get back, Life has a way of interfering with pleasure. At any rate, I think I can rephrase my question since I have no idea how to upload my work. How do I make rounded corners/edges? Not square, nor beveled. Use the default cube that Blender opens up with. How can I make those edges round instead of abrupt 90 degree turns?

Bevel makes edges between faces round. Just try a higher Recursion value. Or do you mean rounding off the edges that don’t touch other faces?
