Hi Conrado, Sorry to hear that the 'Exporting from Archicad' video isn't working for you. But yes, the video shows how to export your Archicad model to IFC 2x3 format. I'd say that the most reasonable workflow is to export the structural, piping and ductwork in separate IFC's. This approach can offer some advantages later on, for example when handling changes of conflict results. Please go through also the Design Coordination Guide, which gives suggestions for your design coordination process http://www.teklabimsight.com/helpcenter/designCoordination.jsp Thanks, Heikki
