This article explores the functionality of Graphisoft’s new BIMcloud service, which was launched towards the end of last month in Tokyo, Japan. It looks at how BIMcloud is different from the BIM Server technology that was introduced in 2009 in ArchiCAD 13 to better support model-based collaboration, the problems it was developed to solve, how it can support collaboration by the extended design team and through mobile devices in addition to traditional computers, its deployment options, and additional capabilities.

I am glad to hear of this new functionality to share large Graphisoft models. I would like to hear more about the ability of Graphisoft to integrate with other functional design and analysis programs that are needed by the other members of the project team (including FM).
