The openBIM webinar was extremely well done. Levente and his team demonstrated the data flowing between Archicad for architecture, Tekla for structural engineering, and DDS cad for MEP . The model data was exchanged in IFC format to and from each program as it would occur in a real project like the housing project in Norway by Rift Architects which was used to demonstrate the process.
Tekla BIMsight was also used to demonstrate their free to everyone clash detection. All disciplines can upload their models and any of the team can do real-time clash analysis.
This was the most exciting webinar demonstrating BIM as it IS used since the Eureka Tower talk back in 2004.
