how to transfer items from one file to another archicad 18

[Andrea966]

hello to all, the problem I have and that I can not transfer an element created in a file of archicad 18 in a new file.
I'll explain. in a file I designed a cottage, now I would like to "copy and paste" into a new file some elements of this cottage.
Could someone please explain to me step by step how to proceed?
Thank you in advance for the answers.

Hello, everyone, I managed to solve the problem. I'll explain the procedure in case someone needs it.
First of all, they select the elements to be transferred (they select them in the plant and not in the 3d if not, I do not know why, it does not work).
selected items go to archive/external content/save selection as form.
Saved the module, I open the other file where I have to place the saved items and drag the saved file into the archicad work screen and place the items.
