The layout x and y coordinates of the department are the column and row coordinates of the department rectangle in the rectangular block layout. For a new project these coordinates must be set to zero unless the user wants to specify a given layout. The y coordinate indicates the row or horizontal layer in the block layout, starting with one for the bottom row and increasing for higher layers. The x coordinate indicates the position of the department in a particular layer or row, starting with one for the leftmost position and increasing towards the right.
