Usage

1. Get the wand from the creative inventory or /give it to yourself.
2. Right click when you are looking at a block (it has quite a long range)

3. Choose which options you want. Then click the type of shape you want.

4. Follow the instructions for the shape.

5. Presto!

Tips

Most shapes follow the same steps.

1. Pick the block, by right-clicking a block
2. Go to the start point and right click
3. Go to the end point and right click.
4. That is all

For things like spheres your endpoint will determine the radius of the sphere.

For a vertical cylinder for example you want to choose the center point, move horizontally to the radius you want, then move up the height you want.

For a wall your first click is one corner of the wall, your second click is the opposite corner.

Undo

You can undo your last action by choosing "undo last action" in the menu. This works on all shapes but the cuboid. Note that the undo buffer is for 1 action only. So you cannot undo more than one action.

There is one issue to be aware of which is that sometimes it detects the wrong block. The chat will indicate which block you have picked so make sure it is the one you want before you continue. If it is wrong then press cancel and try again after moving position slightly.

Bonus

There is also a Emerald Block Pickaxe, which in survival mode lets you break blocks really fast. Even bedrock, with drops.
