Do this command while holding the item you want to be used as the "brush" (meaning every time you right click with this item, it will create a sphere or whatever your brush is set to) /brush sphere (block) (radius [1-5 limit]) Or, //sphere (block) (radius) which will create one individual sphere. You must look at the spot you want the sphere to appear. You may need to experiment and //undo until you get it in the spot you want. (the sphere can't be more than 400 blocks, that's the world edit limit) If you want the sphere to be hollow on the inside, add an h //hsphere (block (radius) Let me know if that answers your question
