Symmetry
by DevReaper0
Symmetry is a Fabric addon for Litematica that draws mirrored copies of a schematic as holograms while a builder places or breaks blocks.
What it does
Symmetry works only in Litematica and requires Litematica and MaLiLib on Fabric. Once a schematic is loaded, its symmetrical builds are visualized in real time, so a builder sees the mirrored result before blocks are placed. The default hotkey, R, symmetrizes the current area selection.
The mod is client-side only, so players install it alone and servers do not need it. Its options are added to the Litematica configuration screen. A setting called symmetrizeIfSelectedPlacement decides whether the hotkey also triggers placement of an already selected schematic, and ignoreServerSymmetryEdits stops block updates from the server from changing Symmetry's schematics on the client. Commands issued to the server, including setblock and fill, are always executed on the server side.
Symmetry is released under the MIT License and its source code and issue tracker are public. Files are published for Fabric only, for Minecraft 26.2 and 26.3, with 0.1.1+26.3 as the latest build, first released on 2026-07-08 and last updated on 2026-09-24.
Key features
Real-time symmetry preview
Mirrors of the loaded schematic appear as holograms, showing the symmetrical build as it is placed or broken.
Symmetrize selection hotkey
The default key R symmetrizes the current area selection, and the key can be changed in the controls.
Schematic Edit tool behavior
A setting called symmetrySchematicEditBehavior controls how the Schematic Edit tool treats schematics that Symmetry restricts.
Placement safeguard
The option symmetrizeIfSelectedPlacement guards against accidentally creating duplicate schematic placements.
