NOTE: Tiles are numbered from the beginning of the cell, starting at the tile closest to the ITC end of the module. Count every other profile to count the tiles. Odd tile layers start at the cell boundary (count from the first profile), even tile layers start with a spacer plate (count from the second profile). The tile counting stick makes it easier to locate the tiles.
