From Autodesk Labs: Project Storm for Revit Structure

Project Storm for Autodesk Revit Structure is a technology preview that provides cloud-based structural analysis to structural engineers as a part of the BIM process. With Project Storm, engineers and designers can extend design models from Revit Structure to the cloud for structural analysis from directly within Revit Structure.

Results can then be visualized and explored within Revit Structure and disruptions to workflows are minimized by performing analysis in the cloud as users continue to design.
