Update global node and link groups
==================================

The Update global node and link groups function is activated by selecting the Update global node and link groups item of the :ref:`Network Menu<network_menu>`, when a network is in :ref:`Edit Mode<edit_mode>`.

The Update global node and link groups function works by updating the user created node- and link groups globally for all classes in the network, such that each class will consistently contain the same groups. This has the side-effect that when the network is later saved in the .net format, the node- and link groups of the top class will be consistent with the groups of all other classes.
