Abstract
A grid is often used as a reference line to determine the position of building components, but, the functions of grids are recognized vaguely. The author focused on the layout of panels such as ceiling tiles, and analized the layout of panels on the grid which is shifted half from the planning grid. By fitting the reference line drawn on the axis of the tiles to the original planning grid, we can get the same layout. It means that the axial discipline is appliable not only to the partitions but also to the building components of panel type.
