First of all I would like to say hello to everyone, cause it is my first post here

I got a little problem - I received recently a complete project - scheme and a PCB project, but the PCB is made not well enough so I need to design it from the begining. The problem is that I cannot transfer the elements to the new PCB sheet, because AD does not see the footprints.
Is there any possibility to extract footprints and elements from schematics to brand new library? I heard somewhere about this possiblity, but I don't know where to search for it.
I am not keen on attaching multiple libraries found in the Internet or draw new footprints..
Please, if you can help me - answer

Thanks in advance.
