Circles, spheres, spiral staircases, arches, towers, pyramids. Exactly where every block goes.
Why this is even needed: Minecraft only has square blocks, so anything round has to be faked by stacking squares in just the right stair-step pattern. Getting that pattern right by eye is the headache — this tool does the math so your circles, spheres and staircases come out perfect.
For 3D shapes (spheres, domes, towers, spiral staircases, pyramids) you build one layer at a time: the 3D preview shows the finished build with a gold band on the layer you're working, and the layer view below it shows the exact pattern to place at that height, with Up / Down to move between them. Blocks from the layer below show as a faint ghost so you always know where you are, and blocks you tap off grey out in the 3D preview too — you can literally watch your tower fill in. The block counts tell you how many to gather first.
The spiral staircase generator makes real climbable spirals: every step is walkable from the one below, one step per block of height, clockwise or counter-clockwise, with an optional center column. The arch generator draws the front view of a perfect arch for doorways and bridges — add legs to turn it into a full bridge span. The tower generator stacks a circle to any height, with optional battlements for the castle look.
