Block Round vs MC Circle

Block Round is a free browser tool for making circles, ellipses, spheres, and ellipsoids with Minecraft block textures. Its 2D modes offer Euclidean, Bresenham, and Threshold algorithms; the 3D modes include X, Y, and 45-degree diagonal cuts, with a 3D preview. Users can choose blocks such as Grass Block, Dirt, Stone, Oak, Diamond, Sand, and Gravel, or a Random mix. The tool exports 2D figures as PNG and 3D figures as Sponge schematic v2 files, which WorldEdit, Litematica, and MCEdit can import. It runs in a browser without installation, an account, or a backend, and works offline as a PWA. Settings last for the session and reset to defaults after a reload. A technical math companion is available in nine languages, with each PDF described as at least 25 pages. The project states that its code, layout, design system, and sound engine are All Rights Reserved, and says it is not affiliated with, endorsed by, or sponsored by Mojang Studios or Microsoft.

MC Circle is a web planner for Minecraft players who need block-by-block layouts for circular and curved builds. It generates charts for circles, ovals, half circles, and domes, with outline or filled views and optional grid lines. Numbered rows and columns guide block placement, while block counts and stack estimates support material planning. The main generator accepts sizes from 3 to 128 blocks and states support for Java and Bedrock editions. Plans can be downloaded as PNG files, copied as charts, or shared through links. The site also provides sphere plans with hollow or solid modes, layer counts, and per-layer block plans. Its coordinate output and layer-by-layer view help translate designs into builds. MC Circle runs in a browser without login, registration, payment, or subscriptions. The free plan is listed at free.
