The Autodesk Revit Reader allows FME to read Revit Export files (.rvz) created by the FME Revit Exporter add-on for Autodesk Revit, which currently supports Revit 64-bit versions 2013 and 2014.
The FME Exporter add-on is only supported in 64-bit FME.
The Revit reader produces FME features from a selected subset of exported data, filtered by data view.
The value for the Reader Dataset is the path to the .rvz source data file.
