Design Options and Legend Components

[Redrunner92]

When I changed a Design Option to primary, a handful of errors popped up. Most of them I anticipated, but these errors about Legend Components are baffling me. I don't have Legend Components of any of these walls in a Legend. Also, since I cannot use the given ID #s to select objects, I am guessing these IDs refer to wall Types and not wall Instances. Does anyone know why errors about Legend Components are appearing, especially errors of the magnitude "must be addressed"?

Further info:

When I made the selected option primary, Revit duplicated a bunch of wall and floor types "to avoid duplicate names." I promptly deleted these unneeded duplicate types. Before I exited the errors menu, though, I noticed that these duplicate types are what the errors are addressing (note the "2" suffix in the wall type on the shown Legend Component error). This process of duplication may be a hint at what is going on to generate these un-ignorable errors. I don't know why this whole process of duplicate-then-cause-errors is happening.

A handful of errors regarding Legend Components which have no instances in the project

I cannot use the element IDs to select anything. This leads me to believe these IDs belong to Types of walls rather than Instances of walls.

I've had those before. Typically with Model Groups. In that case, it happens when a new System Family Type, such as a Wall Type, is introduced into the Project (via duplicating an existing Type and modifying the assembly of the duplicate)  while INSIDE Group Edit Mode.  It's generally a "no-no" to introduce new Families into the Project while inside Group Edit Mode. You should Edit and ADD Families that exist already.

Good to know about Groups, I'll keep that in mind. In this case I am not dealing with Groups; nonetheless, it may be the same issue since both Groups and Design Options have their own editing modes which isolate included objects. It is curious that Revit duplicated the types itself, then caused a series of errors based on its own action. Any idea why it duplicated the Wall Types when I changed which option was primary? It acted like I copied and pasted a Wall Type with an identical Type Name from another project.

You duplicated a wall type while editing a Design Option.  Do it while you are in the main model instead.

[Redrunner92]

No I did not. Revit duplicated them when I clicked "Make Primary." I know not to duplicate a Type in a specific model mode (Groups, Assemblies, Design Options, etc.).

Sorry but I work with design options on every project and have never had the error you described when Make primary / Accept primary.  Can you show the wall type list prior to Make primary?

It seems that you're using Revit 2020. There have been improvements and patches to the options functionality since then. I've had a project where I couldn't change the primary option in 2020 due to some dependencies. After upgrading to 2021 it went fine.

[Redrunner92]

Here are the wall types as you requested. I also attached the errors and warnings list in case you want to dig deeper.

I was able to proceed past the errors by checking the boxes for each of the Legend Components and clicking the "Delete Checked" button.

Before I clicked "Make Primary"

After I clicked "Make Primary". Note the duplicates with suffix "2"

Good to know! Thank you for sharing 🙂

I see the "2"s.  Are you saying that the operation created these walls?  

...sorry, didn't see report. Looks like they were created to avoid conflicts.  

....again: similar to Model Group behavior I described before.  Fix Groups is an option in those cases.  Looks like you didn't have the option in this case.

In lieu of this, I am wondering why conflicts arose when I changed which option was primary.

Not sure what you are asking. The operation found and resolved a conflicts automatically.   Basically, it did want "Fix Groups" does, but without giving you the option.  

[Redrunner92]

I'll word it another way: what are the conflicts which happened? There were no conflicts prior to when I clicked "Make Primary".

If I had to guess... The only way to move elements between design options is copy/paste. I assume that is how Revit also moves elements between design options make accepting primary or similar processes. I don't know how things work on the back end but it could be that the "Primary" label for a design option isn't as simple as a check box for Revit. It may have to create a new option to replace the previous primary option and copy/paste elements between those options. That could be where the error come from.

[Redrunner92]

That makes sense. Even though this isn't a confirmed answer, it seems most likely out of all the possibilities I have thought of. Thank you!
