This is how I did what I think you want. Because it rotates around the center of the mass of the object as @istvan stated. I made a reference line 2x the radius of the axis line used to make the 10 degree section and then use that as the axis line (this would be the diameter of the circle) to move/copy with the rotate arrow 90 degree for each of the next sections. The only thing is it also copies the center line but you can just delete it later. Hope this helps sorry if I confused things.
