Zone Attributes Dialog Box
Use the Zone Attributes dialog box to define how Open Plan should display zones in a network view.
If you enable the zoning option for automatic placements, you can have Open Plan group activities into horizontal bands based on one or more criteria that you specify.
Once you define zoning and perform automatic placements, you can treat the zone headers as annotations to the view. In other words, you can edit, reposition, and resize zone headers just as you can annotations. You can also attach zone headers to activities so that a header moves with the specified activity.
