Revit import to Energy Simulator

Hi,

I am trying to import a Revit Drawing in to Energy Simulator.

I read in some answers to this question and I trying to import a .xml file, but when i import I am seeing the following error message - REVIT MASTER.xml, could not be loaded. I also didn't see the option to import an .xml file in the drop down list of files to import.

How to import a Revit File in to Energy Sim
