Key Features
Blueprint Blocks

Blueprint blocks feature unique replacement mechanics. When clicked with a block from player's inventory, the system automatically finds all connected blueprint blocks of the same color. If player has sufficient materials, all connected blocks are instantly replaced. In crouching mode, only one block is replaced, while empty hand interaction while crouching displays required block count for complete replacement.
Pencil

The Pencil allows placing unlimited blueprint blocks. Crouching interaction opens color selection interface. The chosen color determines the hue of placed blueprint blocks.
Eraser

The Eraser quickly corrects placement errors. The tool instantly removes blueprint blocks: normal use removes single block, crouching removes all connected same-colored blocks.
Brush

The Brush operates on World Edit command principles. The tool remembers two spatial positions, then executes commands for generating large blueprint block quantities.
Command /cbrush help displays available operations.
Available brush commands:
Recolor - Changes blueprint block color from first to second
Fill - Creates cubic area with blueprint blocks
Walls - Forms blueprint block wall
Circle - Creates blueprint block circle
Cylinder - Forms blueprint block cylinder
Sphere - Creates blueprint block sphere
Pyramid - Forms blueprint block pyramid
Iron Scaffolding

Iron Scaffolding represents upgraded version of standard construction scaffolding. Breaking one block automatically removes all connected scaffolding in every direction! Clicking scaffolding with same block instantly teleports between top and bottom elements. During placement, block automatically positions itself in nearest available spot, while crouching places below current block.
