The projector and the board
The armor stand becomes a projector at the corner of the build, with a board that tells what to build.
Where the build appears
The projector stands one block out of the build's front left corner, out of the way of its blocks. Facing the armor stand, you see the build's best side (the one our videos show) rise behind it and to your right.
The build's ground is level with the armor stand's feet: what it has under its ground, foundations or a cellar, goes into the ground. It snaps to the blocks, wherever the armor stand stands in its block.
TipTurn it, mirror it or move it from the menu (Placing the build), or give it fixed coordinates on the site.
The projector
A small projector on the armor stand's block, its head towards the middle of the build, with a short beam of light that fades out before the build: it never shines across your screen while you build.
Hide it, and show it again, from the Build tab of the menu: the build stays.
The board
Over the projector, 4 blocks up, always facing you. It rises with the layer you build, to stay over it.
- The title row: the build, and the view: Whole build, Step by step, the layer mode (All below, This layer only, All above) or From layer N.
- The panel: the view (the whole build, a layer, a step), its materials, most used first, and how many each needs, in stacks: 3×64+12 is three stacks and 12, 1SB a shulker box (27 stacks). What does not stack, buckets or beds, shows its number. Past 8 materials: Other blocks.
- Left, the checker on: what is left to place, material by material.
- The checker's row: Missing and Extra (blocks in the way), All placed, and AUTO when the next layer comes by itself.
- Layers finished: how many layers of the build the checker found complete, and ✓ This layer.
Hide it, and show it again, from the Build tab.
TipSeveral projectors: the menu and the keys act on the nearest one, up to 48 blocks away.
