Hello,
I export my model from Revit to Model Editor and from there I export IDF file for OpenStudio and somehow in between it changes the Z origin of my spaces and my model is up in the air eventhough in Model Editor I choose the basement and set “Ground contact” to “true”. Does anyone know how I can fix that?
This is happening because of how the model is created in Revit. Try to use the “Reset Coordinate System” command in the Model Editor and re-export your model.
