Sometimes Konstru will display changes you did not expect or you did not even apply yourself. For example if you download an ETABS Model into Revit, change an attribute and push changes back to Konstru, there will be more changes than the attribute you just changed. Why is that? Every platform works differently and to put it simple: Revit just doesn't work like Etabs.
When uploading from Revit, Konstru will automatically add an attribute called Join for example. This is a very Revit specific attribute which stores join settings for members. The join attribute won't help you in Etabs but it will make sure your Revit Join settings will persist and you won't have to apply them again. Revit modelers know about join settings but a Etabs user might not be used to it.
