Groups allow the user to organise a set of inserts into a container without having to create another object insert. Using groups allows the user to hide or show sets of objects with only one click of the mouse or to move them as a whole.
Groups can contain user information much as inserts can.
The visibility of groups can be set making it easy to hide or show multiple inserts within these groups.
When adding a group the current object selection can be placed into the group by selecting Move Selected Inserts into Group.
