Litematica Schematic Editing (Rebuild Mode)

The Edit Schematic mode allows you to modify the blueprint itself without changing the actual blocks in the world. This is useful for fixing errors in a downloaded schematic or updating a design.

• Adding Blocks: Place blocks against the hologram while in Edit Mode.
• Removing Blocks: "Punch" the hologram blocks to remove them from the schematic file.
• Replace All: Set a hotkey for schematicEditReplaceAll. Hold it and right-click a block in the hologram with a new block in your hand to swap every instance of that block type in the schematic.
• Storing States: Use Alt + Middle Click on a block in the world to "copy" its exact state (including orientation and NBT) into the Edit tool for precise placement.
