RFA import from Google 3D Warehouse

AECOsim Building Designer V8i (SS6)

Version 08.11.09.863

Hi everyone,

I have just downloaded some doors from google 3D warehouse and I intend to import them into the ABD catalogue. Can someone please guide me on how to go about this since my model does not have a .rfa extension.

I welcome any suggestion/s

Thank you
