Reducing and branching connections have two line sizes. This separate sheet on the summary is to list the relevant schedules per line size combination.
The large table or spreadsheet in the middle is the summary of the branches which gives further details of the reducing and branching connections. The layout of the window has much resemblance with a spreadsheet with cells. The branches are organized per type and displayed in a grid. The types can be for example: tees, weldolets and stubons. The grid will show horizontal the header size and vertical the branch size.
The grids will split in separate subgrids when the number of line sizes do not fit the summary page width.
