## **Features**

### **Symmetric at any size**

Cell centers sit at half-block offsets, so even diameters come out balanced instead of one block wider on one side — the usual failure of hand-drawn circle charts.

### **Sphere layer by layer**

A sphere is shown one horizontal slice at a time, with the block count for that slice and for the whole shape, so you can build it course by course.

### **Copyable grid**

The layer copies as plain text with # and . — paste it into a note, a schematic tool or a chat message for someone building alongside you.
