RoundThing
Never build ugly circles again! RoundThing is a Minecraft (Paper/Folia) plugin that visualizes perfect, block-snapped circles, spheres, and lines with particles as the ultimate building guide.
This plugin is your personal architect for all complex construction projects. It helps players visualize mathematically perfect shapes by displaying a grid of particles exactly where blocks need to be placed. The result is flawless structures without the headache. 
✨ Features
- Three Shape Types: Create detailed Circles, Spheres, and Lines.
- Block-Perfect: Particles always snap to the center of a block, creating a clear "stair-step effect" as a perfect building template.
- Full 3D Control: Freely rotate circles in 3D space! Tilt them on the X and Z axes (
-90°to+90°) to create vertical rings, diagonal platforms, and more. - Thickness & Filling: Create thick rings or completely filled disks and spheres.
- Persistent Storage: Every shape created by a player is saved and survives a server restart.
- Server Protection: A configurable per-player particle limit prevents the server from being overloaded by too many particles.
- Fully Configurable: Admins can adjust the limit at any time in-game or in the
config.yml. - Multilingual (i18n): Automatically adapts to the player's client language. (Supports English, German, Spanish, French, and many more).
- Intelligent Commands: Thanks to tab-completion, commands, shape names, colors, and coordinates are suggested as you type.
📦 Installation

.jarfile from the Releases Tab. - Place the
