3D Block Builder
Your ideas. One brick at a time.
How to build & keyboard controls
Click or tap to place a brick. Aim at the top of a brick to stack. A red preview means the piece overlaps another brick or is outside the board. Bricks need at least one point of support.
Use Select to tap a placed brick, then tap a clear location or another brick to move it. Drag to turn the view; dragging never places a brick. Scroll to zoom. In Camera mode, use two fingers to pan and pinch to zoom. Right-drag pans on a computer. Paint changes a brick’s color; Erase removes it. Unsupported bricks stay in place so you can freely edit your creation.
B: Build · S: Select and move · P: Paint · E: Erase · C: Camera · R: Rotate · Ctrl/Cmd+Z: Undo · Ctrl/Cmd+Shift+Z: Redo. Save on this device or download a build file to keep your work.
