Level Groups Dialog
Used to define a group of levels to use as filter criteria.
Opens when you right-click on a filter name, then select Level Group in the Level Manager dialog.
Note: Level Groups created in OpenUtilities Substation V8 2004 Edition are not backward compatible to earlier versions. For example, if you create a group to a DGN in OpenUtilities Substation V8 2004 Edition and a group by the same name that was created in a earlier version already exists, the group will only exist during the current session and will not overwrite the old group.
