Rotation of an extrusion

Hello,

So far with CamBam I have been self-educated, but I need a little help on this one. I am trying to mill a 3D profile, and I am having trouble orientating the piece so that the router is positioned on the correct axis to do so. Is there a feature that I am missing or a process that I am unaware of to do this? So what I am trying to do is make this shape in the first picture. It's just a 2D shape. So I the flat part is the "bottom of the piece. I am trying to mill the arcs on top. I extruded the solid, and now I and it extruded in the positive direction or towards me. Now I want to lay the piece over so the flat side is actually on the bottom. How can I do this? I have included everything below. Thanks in advance!
