Unify in Design Model

So in Dataset Explorer>Drawing symbology, does the default 'Unify with Self' in Section Unifier and F&R Unifier cause Forms to visibly Unify in the Design Model, even though Section Unify Toggle and F&R Unify Toggle are unchecked?

BTW, what's the Generate 2D column for?

Forms do not unify in a wireframe 3d view.

But you can have a 'cut' in a Design Model. By Clip Volume (unified but not resymbolised if I remember correctly) or by a Building View recalled from the Mini Tool bar or  View Attributes>View Setup. Unified and resymbolised.

I opened all my dgnlib files and modified and cleaned them of garbage

This also allowed me to see all that were used and why.  some I have renamed and not using

Fabulous! How to go about that?

I don't even know how to find out what dgnlibs are affecting my Workspace, from various sources;

how to tell what they do and whether they're vital to the functioning of BD/ABD;

how to open and edit them.

Are dgnlibs necessary at all? I'd still like to start An empty Workspace? without any, then build back up as and when I understand what I'm doing. it's been such a time waster!

To recap, it seems my Design Model has somehow become a Saved View, or is working within a Clip Volume. Everyone says those are the only way that Unification will be visibly happening in Design Model - right?

Well, there's nothing in Saved Views dialog, and AFAIK Active Clip Volume is deleted. Any other places I can check, whether any such exist?

Unification happens when View Attributes>Building panel>Forward>Unify is checked. Wireframe unifies too.

But even when unchecked, some elements, maybe just one Level (or Part?), remain unified.

In View Attributes>View Setup panel>Saved Views dropdown, there are 2 choices:

View Name: Preview ... Model Name: Design Model, and

View Name: Origin, ISO ... Model Name: Default.

If I click either of these, everything disappears from screen, although all Levels remain On, and the only way back seems to be reboot.

What are these, 'Preview/Design Model', and 'Origin, ISO/Default'? Maybe the first is legit, but the second causing trouble? See how they feature in the mystery-message clip, attached

Steve said: "I can't say *how* View 1 was promoted, but it certainly is as you've found (the Demote button).   None of the other view windows are, just View 1.   What's odd though is that you have the Building tab in View Attributes but not the Clip Volume settings that would normally accompany it."

To me, it affects all Views, not just View 1.

New info, this unification only happens when I open this file within

User: Building Designer ... Project: BuildingTemplate_NM_Full [tom 1] ... Interface: tom.

This unification doesn't happen when I open this file within same but

NM_Full (i.e. not my customised Project NM_Full [tom 1]).

However View Attributes>View Setup panel>Saved Views dropdown still shows:

View Name: Preview ... Model Name: Design Model, and

View Name: Origin, ISO ... Model Name: Default.

So what could be causing unification only within my customised Project NM_Full [tom 1]?

Service Request (#7000229861)

It's a 'top priority', as it's near impossible to keep modeling, when some of the elements persist in unifying, so can't see what's what. That's even with 'View' (what View?) demoted. Only solution is to open the file not in my customised Project - then I lose all my customised F&Ps.

Your model works fine in my U.S. setup.

Move all your DGN to another location and see if the problem persists.

If it does then it is something else

If it does not then

Move dgnlib files slowly back into play
