Missing library parts - unable to find these items and remove

[cocoloco]

Hi!

I’m trying to start a fresh project while keeping only my pens, layers, layouts, and fills—without any old libraries. However, after removing everything, I now see an alert for 600 missing library parts.

I intentionally deleted everything inside the project, including hidden layers and embedded library parts, so I want them to be missing. But instead of simply clearing them, Archicad keeps showing alerts about these missing libraries. Why is this happening?

The issue is that I know these Archicad library alerts aren’t useful in this case, and I just want a clean start without them. I even tried using a template file, but it still loads the 600 missing libraries!

Is there a way to import only pens, layers, layouts, and fills into a completely new project without triggering missing library alerts? Or any way to permanently remove these missing parts?

IMPORTING MASTERS THROUGH organizers 

I Should also mention I was trying to make a completely new file and add the masters through "organizer" because on some forum it mentioned to use that, however I don't have in my archicad 28 the option to import anything. Thought I would mention it. I feel defeated

Whooaaa. I ended up making a new archicad file and merged the old one through "interoperability".  Although I have to adjust a lot (from the new arch file) -  it integrated everything from old file such as fills, lines/pens, and masters. Thankfully it fixed all the missing files

Expand the 'Warnings' section in the Library Manager and you will see what libraries the missing objects are form and if they have been placed in the model.

They could just be missing fro your favourites and not actually placed in the model.
