Summer 2015 BIMx release features:
Cloud storage has become the obvious choice of multi-platform and mobile users, especially for users constantly on the go. BIMx is widely used in the AEC industry for design presentations to project stakeholders, and the ability to sync a project model to the latest version is essential in an on-site situation.
Closing the gap between file management apps and BIMx, the document picker allows users to link popular Cloud storage services like iCloud and Dropbox to the app. As a result, downloading and opening BIMx models becomes seamless.
