Draws a hollow box of blocks, optionally filling the inside with another block type. After entering the command you need to mark 2 opposing corners of the area. You can do that either by clicking the blocks (building or deleting worlds), or using the /Mark command. The results of /CuboidH can be undone using /Undo.

/CuboidH

Draws the box made of whatever block player is holding. The inside is left untouched.

/CuboidH OuterBlock

Draws the box made of a given block type. The inside is left untouched.

/CuboidH OuterBlock InnerBlock

Draws the box made of a given block type. The inside is filled with InnerBlock type. If you want to hollow out the inside, use "air" for InnerBlock.

Customizing /CuboidH behavior

• The volume of blocks that can be drawn at once can be limited per-rank. See "Draw limit" field on ConfigTool's Ranks tab. Alternatively, set the "drawLimit" attribute on the <Rank> tag (if you are editing config.xml manually).
• Being able to undo a command requires storing a backup an area of the map. This may take up significant amounts of memory. By default, fCraft limits /Undo to the first 2,000,000 blocks that are drawn. You can change this (or remove the limit entirely) via MaxUndo config key.
