extrusion

Hello all, I decided to give Alibre atom a go with their sale over this last weekend, and have run into my first issue/question. I'm trying to do a simple extrude cut with two concentric circles upon an existing extruded rectangle. The smaller circle cutting all the way through my design...

Can you fillet the edge of an extruded spline shape in Alibre aggressively. Here is a simple example that was done in another program and imported into Alibre. I tried this in Alibre with no success. I was able to get a smaller radius fillet in Alibre.
