Effortless Structure
by huskcasaca
With Effortless Structure installed, players can place, break and use blocks or items in batches, arranged in lines, grids or other shapes.
What it does
The mod speeds up building by applying one action to many positions at once. Blocks and items are placed, broken or used in patterns, and the correct items and tools are consumed for every position, so survival costs stay honest. Holding the left Alt or left Option key opens a radial menu where the build mode is chosen.
Effortless Structure also includes array and mirror transformers, a clipboard for copying structures and pasting them, a block randomizer driven by a pre-defined list, and permission controls for server owners. It is published for Fabric, Forge, NeoForge and Quilt, with files for 1.17.1 – 1.21.3, and it is released under the GNU Lesser General Public License v3.0 only, so the code is open source. Client and server both need it, and it stays compatible with pure vanilla content, so it adds no new items of its own.
Key features
Batch placing and breaking
One action places or removes blocks across a selected area, following the chosen shape.
Array and mirror transformers
Repeats or reflects a build along an axis, so symmetrical designs need one set of placements.
Structure clipboard
Copies blocks and entities from one area and pastes them elsewhere, including between worlds.
Build mode radial
A radial menu opened with a held key switches between the available build modes during play.

Use cases
Large builds in survival
Players fill walls, floors or grids in one action while consumption still follows the items in the inventory.
Server building projects
Server owners use permission control and the clipboard to let members copy and paste structures without wider access.
Who it’s for: Builders who work on large survival projects, and server owners who want shared building tools with permission control.
