Moving Instances Outside a Virtual Hierarchy

The Design Planning and Analysis tool can automatically resize the area boundary of a virtual hierarchy to accommodate an instance (or instances and figGroups other than row region) that are moved outside the boundary. If adjusting the area boundary of the virtual hierarchy causes its area boundary to go outside the higher-level virtual hierarchy that includes the adjusted virtual hierarchy, then the boundary of the higher-level virtual hierarchy is also automatically adjusted. To allow this automatic area boundary adjustment of virtual hierarchies across the hierarchy, select the Auto adjust area boundary option on the Design Planning and Analysis Options form.

To automatically adjust area boundary when moving an instance outside a virtual hierarchy:

1. In the Design Planning and Analysis toolbar, click the Increase Display Depth button to increase the display depth stop level value to a value greater than 0.
2. In the Virtual Hierarchy Options form, select the Auto adjust area boundary option and click OK.
3. In the layout canvas, select an instance inside a virtual hierarchy and drag it to a position outside the area boundary of the virtual hierarchy.
   Flight lines appear on the canvas, showing instance connections to other objects still inside the virtual hierarchy.
4. Drop the selected instance outside the area boundary of the virtual hierarchy.
   The area boundary of the virtual hierarchy automatically adjusts to fully accommodate the moved objects.
   Note:
   
   • If the area boundary of the adjusted virtual hierarchy now falls outside the area boundary of the higher-level virtual hierarchy, the area boundary of the higher-level virtual hierarchy is also automatically adjusted.
   • Non-rectangular area boundaries are not automatically adjusted.
