No good view could be found - Can't see an element (Not related to warnings)

[AGYN2022]

Hello, 

I can select an item using "Select Elements by ID" but I can't see that element. I tried to make a 3D view and have all my visibility settings turned on but still can't see the elements. Tried to have my 3D view in different phases. But no luck. All the worksets are also on including the ARCH Placeholder but nothing. Here is a screenshot of the properties of the element: 

Can someone please help? I am very frustrated

what are you trying to see a imported model / object a wall?

[AGYN2022]

There are supposedly mechanical equipment that should not be in the Arch model. This is one of them

it looks you have Design Option active . Maybe the entity is placed in another option...

[AGYN2022]

Thanks for the suggestion. But I can select the element, which means that it is inside the active design option. If it were not inside the design option, I would have seen an error that it couldn't be selected. My problem is that I can select the element but can't see it.

How do you know it's placed in the project?  Does it show up in a QTO schedule? 

[AGYN2022]

You're right. There is a high probability that it is just a family loaded into the model but has never been used in the project. But why does it have an id then? Can a family that has never been used have an id?

How do I have the list of the mechanical elements in the QTO schedule by their ID?

I'm with @constantin.stroescu on this. Design Option? 

[AGYN2022]

I checked the other design option. There was nothing inside it. So it can't be design option.

Are they RFA Families that you have created or are they imported CAD files>?
