Immediately set up a live, real-time visualization between Revit and Lumion. You will need Lumion 8.3 (or newer) and Revit 2015 (or newer).
Now, you can view and change your Revit model in real-time in Lumion, as well as export a Collada (.DAE) file from Revit and import (or re-import) it seamlessly into Lumion. The Lumion LiveSync for Revit plug-in includes two features - LiveSync and a Collada (.DAE) exporter.
