What is actually a "Graphic Group"?

Hi.

I see 2 ways to create a Group in MicroStation:

- Group

- Named Group.

Group is very limitated because I understand we cannot add/remove elements later. And it is basically a Cell.

I understand that "Graphic Group" is a Named Group...

Because tools such as "Add to Graphic Group" and "Remove From Graphic group" are only for "Named Groups".

There is also "Graphic Group Lock" (ON /OFF) for Named Groups.

Why Bentley differenciates between Graphic Group and Named Group? is not the same? Is the old name of Named Group?

Thanks.

    Graphic Group

    A Graphic Group (GG) is legacy technology — it's been part of MicroStation for decades.  When you create a GG the operation is intrusive — meaning that it modifies the elements being grouped...

    • MicroStation finds the current GG value (it's stored in the DGN file)
    • MicroStation assigns that GG value to each selected element and rewrites the element
    • MicroStation increments the stored GG value

    Depending on the state of the GG lock, you can modify all elements in that group.

    Named Group

    Named Groups (NG) are a 21st century invention.  NGs are non-intrusive — they don't modify the selected elements.

    NGs are much more versatile than GGs.  They have structure, behaviour and hierarchy.  

    Anonymous Cell (Group Command)

    The group command (Ctrl-G) is another legacy tool.  Select some elements, then use Ctr-G to convert them to components of an anonymous cell.
