Cant import .idf to OS (I would like to export to gbxml from idf)

edit

Dear All and @David Goldwasser

Could you please help me how can I easily solve the problem: "File is not valid to draft strictness..."

I just would like to get a gbxml from my building geometry (i dont need the HVAC), but i cant import my idf to OS. (and of course thats why i can export the gbxml).

Thank you in advance!

I found some similar question at unmethours but i can find an easy solution what i could do.
