Sketchup Models (.skp) may be imported into Revit using the Autodesk FormIt Add-in on the Menu. The sketchup file will be converted to a FormIt type file and then used as a reference model to create a Conceptual Mass which can then be analyzed. Sketchup uses faces and more complex models may not be read fully by Revit depending on how layers and materials are set in Sketchup.
Work is ongoing to research and develop support for other model formats.
