PillarPlan: Even Spacing Guide
by SuffixHD
PillarPlan: Even Spacing Guide previews evenly spaced pillar positions along straight and curved building paths before any block is placed.
What it does
A player chooses a start block with P, then adds straight path points along the X and Z axes. Connected sections are planned as one line, and the mod calculates where each pillar belongs so the gaps stay as even as the geometry allows. Positions are drawn as outlines, so the player sees the plan without any blocks changing in the world, and the player places each block personally.
Curved sections are supported. The player presses C to select a guide block, then uses P to set a start point, a guide point and an endpoint that together fix a circle segment. Points on a curve snap to the Minecraft block grid, so they are approximate.
PillarPlan runs entirely on the client, so only the player using it needs the mod installed; a server does not. It depends on Fabric API and is published for Fabric only, with a single build, 0.2.1 for 1.21.11, released 2026-08-13 under the MIT License. The mod is not open source.
Key features
Adjustable target spacing
Press G or K to raise or lower the target gap, and the outlines recalculate at once.
Two spacing types on straight runs
Where perfectly equal gaps are impossible, pillars are spread so that adjacent gaps vary by no more than one block.
Actual spacing preview
An example of the finished build shows the real gap width, so the player can compare it with the plan.
Undo and clear
The latest action can be undone, and the whole plan can be cleared to start over.

Who it’s for: Builders who want a fixed number of evenly spaced pillars, rails or posts along a route, in single-player or on a server where they play alone with the mod.
