Working with Design Partitions Design Partitioning October 2019 15 Product Version 17.4-2019 © 1999-2019 All Rights Reserved. Figure 1-4 Extending the Partition Areas Component Report – A list of partition based components can be generated using the Preview option in the Options tab when you run the Create Partitions command. The last column in the report provides information on whether the component is shared by more than one partition. Neither the master nor the partition designer can move shared components. Special Instructions – Each partition has an associated notes attachment. The master designer can append a note to the partition to communicate additional project requirements to the partition designer. The master designer optionally can append the same note to multiple partitions. The notes attachment can only append, therefore retaining all history. Placing to DFA driven rules – The partition designer can place components to DFA rules, provided the master has loaded the DFA spreadsheet. This spreadsheet is available to the partition designer in a read only view. DFA rules are not available when components are placed adjacent to components in other partitions. The master designer needs to check for violations along the boundaries. Tip Consider using the Place Manual icon for manual placement as DFA feedback is not available using the generic move command. Another benefit of using the new Place Manual icon is access to the mirror command from the right mouse button.
