Thanks! Using the "Part" workbench instead of the "Part Design" workbench, and using the "Polar array" tool from the "Draft" workbench instead of the "PolarPattern" tool from "Part Design" workbench seems to have done the trick.
I'm now having some difficulty with step 6: Slicing the cube into 9 pieces. It seems like the best tool for this is "Slice apart" from the Part workbench. Is this the correct tool?
If I set the polar array number to 2 (generating two discs), I can slice the cube into 3 pieces just fine. However, if I set the polar array number to 4 (generating four discs), the "Exploded Slice" in the tree contains only 3 pieces, not 9.
The exterior faces of the cube appear to have been sliced by all four discs, but only two discs seem to have actually sliced the solid.
What am I missing?
I think you'd be better off using the Boolean XOR tool from the same Split submenu (if you approach it from the Part menubar in the Part workbench), on your cube and your array, instead of the Slice apart tool.
Then on the resultant XOR object use the Explode compound tool from the Compound submenu.
You'll get a folder with all your sliced parts in it.
