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. How to save Revit project to an older version?īIM applications, including Autodesk Revit, use file formats, which are only upwards compatible - so by default you cannot save ('downgrade') projects to an older version of the given CAD/ BIM application.Īn alternative way of transferring a substantial part of your project ( BIM model) to a previous version of the program is the exchange format IFC (Industry Foundation Classes, specified by IAI). Faster Revit rendering with one plug-in The Lumion LiveSync for Revit plug-in includes two features LiveSync and a Collada (.DAE) exporter. Autodesk Revit 2021 is already installed.
