You can view the page breaks in modeling diagrams and
store the page break information with the diagrams. If you make
changes to the print parameters, such as page size, margins, or
orientation, the page breaks are updated in the diagrams.
You must have a diagram open in the Modeling perspective,
and the diagram must contain elements that span several pages. You
must also have a printer installed on your system so that information
about the printer and printer settings are available for calculating
page breaks.
To view the page breaks, right-click an empty
space in the diagram editor; then click .
