About CircleGen
CircleGen is a free web-based generator that converts target block diameters between 5 and 256 blocks into pixel-perfect blueprints for Minecraft creations. It generates layouts for 2D and 3D shapes including circles, ovals, spheres, domes, and arcs. Builders can leverage an interactive Builder mode featuring layer slicing, step-by-step guidance, and auto-advancing workflow controls. Generated blueprints can be exported as PNG, SVG, CSV, or JSON files, or copied directly as /setblock commands with world coordinates. Built as a static web app with zero backend infrastructure, CircleGen uses midpoint circle algorithm math to ensure full parity across Minecraft Java and Bedrock editions.
