Autodesk just announced IFC file support in Design Collaboration.

With this enhancement, we have expanded the use of Design Collaboration to make it more accessible for companies using IFC file formatted supported tools and workflows; to facilitate interoperability in the architecture, engineering and construction industry.

You will be able to share, consume packages, and generate aggregated views for IFC files:

View IFC data as a single model or in context of the project model in BIM 360 Design Collaboration
Create a Package with IFC data
View a shared Package with IFC data
Understand what has changed between versions of IFC data
Link IFC file from Shared space
Create Issues on IFC data
