Minecraft Circle Generator
Generate a block-by-block circle blueprint, count its blocks and export the plan as an SVG.
Files stay in this browser tab.
How to use it
Choose a diameter and an outline or filled circle. Inspect the grid and material count before building.
Worked example
Create a 21-block-diameter outline and compare its horizontal and vertical symmetry.
What to check
The output is a single-layer block plan. It does not modify a world or use Minecraft account data.
Build a system for this use case
Minecraft build-planning and server administration workstation
Example OpenFactory build prompt
Build a useful minecraft build-planning and server administration workstation on Ubuntu 24.04 LTS amd64, unless the target installer or embedded board requires its explicitly selected OS.
Use Java, a world-planning interface, server configuration templates and backup tooling. Include only the components this workload needs. Use synthetic sample data and placeholders for site-specific domains, authorized SSH public keys and external integration credentials. Create a non-root operator and keep administrative access private. Never put real credentials, patient records or customer data in the image.
Acceptance checks: render a synthetic build plan, validate server configuration and test world-backup restoration; require explicit EULA acceptance before activating proprietary server software. Boot the actual artifact and repeat relevant health, persistence and access checks after reboot. Keep hardware-dependent checks pending until the specified equipment is attached.
Deliver the bootable image or reproducible deployment recipe, the software inventory and a test report that separates successful assembly from runtime verification. Ask for missing hardware, storage and access details before making irreversible deployment choices. Do not deploy into production or erase an existing disk without an explicit target.Your tool inputs and files are not included in the build prompt. Review the draft and press Send in OpenFactory.
