Combo Tools
by m39ko
Combo Tools is a NeoForge utility that lets players place and clear whole areas of blocks with a single action, instead of one block at a time.
What it does
The central item is held in the main hand while the blocks to place stay in the off-hand. Sneaking and right-clicking cycles through 12 building modes, and a green wireframe preview shows exactly where blocks will land before the click. Settings for the tools are configurable, and each preview is drawn so players can confirm the result first.
The mod is built to fit vanilla survival and creative play, saving time on large builds and mining jobs. Every player and the server need a copy of the mod. Files are published for NeoForge only, across 14 release versions 1.21.1 – 26.1.2, and the latest file, 1.3.0, targets 1.21.1. The code is not open source; the author holds all rights.
Key features
Twelve building modes
Single, line, wall, floor, pillar, cube, bridge, stairs, circle and hollow room modes cover the common shapes used in construction.
Wireframe previews
A green outline appears before each placement, showing the blocks that will be set so the result is known in advance.
Walls and floors at size
Wall modes erect 3x3 or 5x5 sections, and the floor mode lays a 3x3 paving area for roads and foundations.
Bridges and staircases
The bridge mode extends a span outward and drops support pillars to the ground, and the stairs modes build a 5-step staircase in one action.
Circles and rooms
A rounded flat 5x5 platform and a hollow 5x5x5 room can be placed at once, for towers, shelters and similar structures.

Use cases
Filling large spaces
Clearing or enclosing a massive room takes seconds with the cube and hollow room modes instead of placing each block by hand.
Quick terrain work
Pillars, bridges and floors let a builder lay out a base or cross a gap without repeating the same placement many times.
Who it’s for: Builders who place many identical blocks, survival players building bases and multiplayer groups that construct shared areas together. Both the server and clients need the mod, so it suits servers that run it for everyone.
