Edit Group
Click the Insert | Group | Edit Group command or right-click on a Group object and select Edit Group to edit the objects in a group. Once in the edit group mode, new objects can be added or existing objects can be moved relative to other grouped objects.
Open Group
An open group is indicated when the bounding box changes from all objects in the Group being selected with a single large bounding box to only one object being selected. When the group is open, the editing and drawing commands operate within the group only. New objects can be added to the group. Multiple objects can be selected, deleted, moved, or edited. Objects outside the group cannot be edited.
Stop Editing Group
Click the Insert | Group | Stop Editing Group command or right-click on the Group object and select Stop Editing Group to end the edit group mode. The Stop Editing Group command must be selected to select and edit objects outside the group.
