I was just wondering if anyone could provide me with an overview of information transfer between Autodesk Ecotect and AutoDesk Revit MEP 2012 in terms of:

- The type of information transferred
- The file format of the information transferred
- The direction of the transfer (i.e. Autodesk Ecotect to Revit, Revit to Autodesk Ecotect or bidirectional transfer
- How user friendly the transfer is

Thank you in advance.
