You can upload as much as you want to Konstru and you will always see your latest upload online. And you might think your model simply gets replaced like on any other BIM cloud service. But Konstru is different. Every time you upload to Konstru, it is actually uploading changes only and not the entire model. If you are looking at your model online you'll see the latest state, built from all your uploads you have made over time. This way every step is captured and its easy for you to go back in time. Konstru's history tab gives you easy access to all historic model versions. We don't want you to get lost between all the Revit, ETABS or Tekla files looking for the right version. Konstru handles all of this automatically while you just have to hit upload.
