About Our Building Tools
Block Circle Plans is an independent tool for turning circle and oval dimensions into a block-by-block building reference. The diagram, material count, row instructions, and exports all use the same occupied squares.
How the grid works
The tool samples a circle or ellipse at the center of each grid square. Thin keeps its four-neighbor boundary; thick uses an eight-neighbor boundary; filled keeps the interior. A square can be occupied or empty, so a smooth curve becomes a stepped outline.
The method is adapted from Jesse G. Donat’s Circle Generator, available under the MIT License. Our grid method is identified as donatj-2d-v1 on exported plans so the result can be compared later. Different generators may use a different grid rule and count.
Made for a second screen or a sheet of paper
Use the row numbers to follow a build, save progress on the same browser, or take a PNG, SVG, or printed plan beside your game. Row numbers are blueprint coordinates; the tool does not read a world or place game blocks.
