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.
A master snap point can be created when editing a group, setting the location by adding a 2D and/or 3D locus where priority snapping should occur, when enabled in Object Snapping. In the Object Info palette of the selected locus, select Master Snap Point. If the master snap point is in an obscure location and you want it to always display when the snap box is over the group, select Show Master Snap Point Outside Snap Box.
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.
