Use the Modify > Edit Group command to edit individual objects in a group without ungrouping them. This command also edits a group of objects that is nested inside another group; each time the command is selected, the program moves one level deeper into the group. See Object Editing Mode for details.
Use the Top Level command when editing nested groups, to return to the main drawing area in a single step.
Select Modify > Top Level.
The program automatically exits all groups being edited and returns to the main drawing area.
