I see 2 ways to create a Group in MicroStation:
- 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?

the worst is that it is one dialog - in my view - "Add to Graphic Group" there you have to switch on the Option "Named Group" . Without you get GG, with the option an NG.
That is confusing.
Named Groups allow dependencies and "active" and "passive" members.
The worst is though that you can not copy that "Named Group" (or create a cell from it) ( it is a longstanding request) - In effect the Named Groups are not useable in practice.
You can copy GGs (it increases the GG Number)
Also - to confuse new users ? - there is the "Group" command which effectively creates an (unnamed) cell. (You can give it a name later in the properties)

I strongly disagree with such general statement, especially because I know users that use NG daily.
It does not mean that NG is not usable for you.
Gerd Eisenacher said:The worst is though that you can not copy that "Named Group"
Similarly to Jon I do not quite understand what do you mean by "copy NG":
Gerd Eisenacher said: (or create a cell from it) ( it is a longstanding request)
I do not recall I saw such request in ideas, but they are many of them, so maybe I missed it.
The request sounds interesting, but is not simple, because NG allows "far referencing", when elements in NG can be from active model, and from direct/nested references. So more conditions have to be fulfilled to allow to create a cell from NG content.
Gerd Eisenacher said:Also - to confuse new users ? - there is the "Group" command which effectively creates an (unnamed) cell.
Well, it's a result of history and only limited "good words" in language. Do you have any idea how one or second tool should be renamed?

MaryB said:When a Named Group is copied...
You can assign a propagation policy to a Named Group.
Bob Rayner said: Opened the Named Group dialog, created a new group, added a few elements. I then copied those elements. They all copy as a named group with graphic group lock on
One propagation policy is just that: the Change Propagation options are: Group Lock — only when Graphic Group Lock is on.

So lets define what the use of each of these groupings is Including use cases.I have a hard time to find examples for some. And maybe how they can be advanced (in ideas)
Jan Šlegr said:I know users that use NG daily
I would like to understand how they are utilizing them.
Jon Summers said:You can assign a propagation policy
OK, can one give me an example of a use case? Is this not very obscure? How do I "see" as a subsequent user how these settings have been done for a particular group?
Gerd Eisenacher said:Is this not very obscure?
I think that Named Groups were devised by Barry Bentley for MicroStation V8i. I don't believe that he intended them to be obscure. As with many things, it's subjective whether something is obscure or arcane; familiarity with NG use will lessen FUD (fear, uncertainty and doubt/Angst, Unsicherheit und Zweifel).
Right, but obviously some (including me) would like to know use cases to then decide whether they are applicable for them. We often "think" we understand - like here - only to hit a invisible wall. Maybe it is my lack of imagination (or intellectual capability...)
Gerd Eisenacher said: Some would like to know use cases to then decide whether they are applicable for them
For example, using a Named Group to populate a Display Set. Now you can control the display of that NG.
Update: I see that you already mentioned this Wiki on that same topic.
Question to Bentley Systems (Eduardo Lazzarotto): that Wiki article was written in 2004 and is archived. Is it invalid for CONNECT? If it is valid, move it to the current MicroStation Wiki.
Vote for this Idea to have that Wiki brought into the CONNECT era.
There are a couple of ideas regarding requested enhancements for Named Groups that are also worth to VOTE for
