I just downloaded and installed Unreal Datasmith plugin in for 4.24. into Revit 2020.2. With a model of 3 walls and a floor, I am getting the below error on export. I see there is post from 2018 that said the issue was fixed. What am I doing wrong?
Object reference not set to an instance of an object.
at Autodesk.Revit.DB.CustomExporter.Export(View view)
at DatasmithRevitExporter.DatasmithRevitCommand.Execute(ExternalCommandData in_commandData, String& out_commandMessage, ElementSet out_elements)
