I have a half 1000 mm hollow sphere with a thickness of 5 mm.

I am trying to cut 2 mm diameter circular dents with a depth of 1 mm on the interior surface of the half-sphere. The dents would be separated by 5 degrees to create latitudes and longitudes such as what you usually see on globes

What would be the most efficient way to proceed with SolidWorks in order to do so.

Thanks!
