Using the BooLean tool to create Cheese

I started by creating both a box and a sphere. I made the sphere much smaller than the box.

I placed the sphere on the top right corner of the box.

I then selected the box, clicked on the drop down list and selected 'compound object'.

I selected Boolean from the buttons, selected 'pick operand b' and then selected the sphere.

The sphere then disappeared and created a hole in the box.

If I had placed the box and sphere differently and selected 'operand a' it would have made the box disappear and a hole would be created by the box onto the sphere.

After making a small hole in the box I decided to turn it into cheese, I made several holes and made it yellow.
