Hole Wizard

I am having problems placing holes with the hole wizard. I'manewbie...

It's really simple. I have a 1" thick boss with anextrudedcut of a hole in the middle.  Lets say it's shapedlike asteel donut with flat faces and no other features applied atthemoment.  I need to know what I have to do to position afewtapped holes on the outer edge facing in toward thecenter. The boss is on the front mid-plane.  I know howtoselect which type of hole.  The problem is entirely ingettingthe holes on that outside edge coincident with the verticalandhorizontal axes of the hole.  SolidworksParts And Features
