How to read the blueprint
Each teal square is one block; each faint cell is empty space. Build it like pixel art: pick a starting row, count the filled squares and gaps, place blocks, move up a row. For big circles, do one quadrant and mirror it — the pattern is perfectly symmetric.
Why circles look stepped
A block is either there or it isn't, so a circle becomes a staircase of block runs that get shorter toward the "top" of the curve. That's not a flaw to fight — it's the aesthetic. Diameters above ~20 start reading as genuinely round; above ~50 they look smooth even up close.
Choosing size and thickness
- Towers: odd diameters (13, 15, 17…) give a single center block — handy for placing a beacon or spiral stair.
- Walls and rims: thickness 2–3 keeps large rings from looking fragile and gives you a walkable edge.
- Domes: generate several diameters (e.g. 21, 19, 15, 9) and stack them following a circle profile.
Material planning
The block count updates live — that's your shopping list before you start mining. A thin ring needs roughly π × diameter blocks; filling multiplies that fast, so check the count before committing to filled floors.
FAQ
Can I make a perfect circle?
No — but past ~20 blocks across, nobody can tell. Bigger = rounder.
Odd or even diameter?
Both work here. Odd gives a center block; even centers on a block edge.
How many blocks will I need?
Watch the live count under the blueprint — it's exact for your settings.
Spheres?
Stack circles layer by layer, or use Plotz for big spheres and WorldEdit's //sphere on creative servers.
Does it match other generators?
It uses the standard midpoint-ellipse fill most builders' charts use, so patterns line up with the classic ones (a 5-ring is the familiar 12-block shape).
