Selection cannot be copied

[Mustafa.Salaheldin]

Hello
I have the shown MEP model:

When I select the model elements and press the copy button, I receive the error message shown.

The selected elements are:

But for some reason the copy fails, any ideas?

This is the Revit build I'm using:

Why would you copy all of that stuff in a 3D view?

Is this copy to clipboard to paste into a different project?

If this is copy within the project, try being strategic with your selection and do it in appropriate views.

If you are in the mechanical discipline, generic models are tricky.

Could you pls click expand button. Revit will show elements which cause the problem

[Mustafa.Salaheldin]

@RSomppi Essentially, I needed to develop an add-in that copies the elements from one file to another, then I hit this exception. When I decided to investigate the original file (the source file to copy) I discovered that in Revit project model, when I select the model elements and press the "Copy" button in the Revit UI I get this error message.

@tawilson Please clarify more.

[Mustafa.Salaheldin]

@ducmap2212 The expanded message has no information.

Hi. Seem like you are copying pinned element

Btw, Can you share this file so that I can make a test on it.

[Mustafa.Salaheldin]

@ducmap2212 I tried to unpin all pinned elements also but there was no change. Let me check if I can share the file as it is from a live project, so there may be some sharing restrictions.

[RSomppi]

Have you tried limiting your selection in order to isolate the offending elements?

[tawilson]

I have seen elements and not be able to select them until I changed to the architectural disclipine. They were plumbing fittings that I believe were made with an addin. I work with an addin that creates generic model tags, and I can select them, but can't use the select all function. I don't know if changing the discipline changes that.

@RSomppi Following your advice, I figured out that the Pipes are the reason.

When I removed them, the copy worked, if I select them only I receive the same error message, but no clue why this happens.

[RSomppi]

I wouldn't have expected it to be the pipes. I copy/paste them from time to time.

[Mustafa.Salaheldin]

@tawilson With cherry picking, I found that a specific Pipe type is causing this issue:

If I excluded this type, copy works, so how can I know the reason?

[RSomppi]

Trial and error?

Find differences from the other types. Adjust parameters accordingly and test again.

I have no problem copying a vertical pipe in a 3D view in Revit 2022 (same version).

Did you try auditing the project?

[Basam.Yousif]

Mustafa, man!

It's probably hosted elements or the datum elements.
Can you copy one category at a time? for testing only?

Call me and let's do a zoom call!

[Mustafa.Salaheldin]

@Basam.Yousif OMG you are already level 10 😁 Couldn't see that coming my friend. Sure, it is my pleasure to investigate that together over a Zoom call.
With Level 10 you should be in the expert elite program already @Maureen.H would you please advise?
