It used to be possible in AC8 to make groups of smaller groups, and then break them apart into the original sub-groups.
On AC9 now, when ungrouping a large group containing smaller groups, it all breaks into single lines, defeating in fact, the whole idea of grouping.
Hope the old feature has not disappeared ! , since really usefull for 2D work.
If anyone has figured this one out, would appreciate the info.
Many thanks,
