Autodesk Revit Architecture 2010 Bidirectional Associativity

Autodesk Revit Architecture offers a unique design approach to ensure that your construction documents are well-coordinated.
With Bidirectional Associativity, managing tags for sections and other detail views becomes a thing of the past. Revit does this coordination automatically for you. Even when big changes are made to the design late in the process, there is no need for drafters to manually update drawings and make sure that drawing keys are still coordinated. The same concept applies when additional details are added to a sheet or when a series of details are moved from one sheet to another. Experience has proven that this manual process can take excessive amounts of time AND is prone to errors.
