Modern’s Build Guide adds a simple planning block for builders who like to map things out before placing the real materials.

Place down a Build Guide block, interact with it, choose a shape, set the size, offset, fill mode, and direction, then toggle the preview on. The mod shows guide blocks where your build would go, with red markers for spots that are already blocked.

It is meant for planning large builds without tearing up terrain or accidentally replacing existing blocks.

Features:

Build Guide block with saved settings
Custom UI, no commands needed
Shape previews centered on the guide block
Hollow and solid modes
Offset controls for X, Y, and Z
Flip/orientation options
Conflict markers for blocked spaces
Preview markers do not replace existing blocks
Settings stay saved on the guide block until it is broken
