Adding Rooms
Click the "Add to Canvas" button on any room card in the left palette to place it on the canvas.
Moving Rooms
Click and drag any room to move it. Rooms will automatically snap together when attachment points (green dots) get close to each other.
Snapping
Attachment points are shown as large green dots on the center of connectable walls. When dragging a room near another, the dots will turn gold and show a connection line when in snap range. Release to snap them together.
Rotating Rooms
Select a room by clicking it, then click the "Rotate 90°" button or press the R key.
Deleting Rooms
Select a room and click "Delete" or press Delete key. You cannot delete a room if doing so would make other rooms unreachable (orphaned).
Why Can't I Delete a Room?
The builder prevents you from creating disconnected sections. If removing a room would leave other rooms without a path to the main group, the deletion is blocked. This ensures your floorplan stays as one connected layout.
