About this Mod

Cuboid Clearer

A powerful Fabric utility mod for Minecraft 1.21.11 that lets you select two positions and instantly clear or fill the entire cuboid area between them.


Features

  • Select positions using /cc pos1 and /cc pos2, or just sneak + right-click any block with a stick
  • Clear areas with /cc clear — hold any tool, drops all items, respects durability
  • Fill areas with /cc fill — hold the block you want to place, uses blocks from your inventory
  • 3x3 Hammer mode via /cc hammer — every block you mine also breaks the 8 surrounding blocks in a 3x3. Durability is consumed per block broken
  • Particle effects — green burst on Pos1, red burst on Pos2, red wireframe outline drawn on clear
  • Safe — never breaks bedrock, stops if your tool breaks, max 5000 blocks per operation
