I've made a demo video at https://www.youtube.com/watch?v=iiLDzNYswGU
There is also a new version for 2016 and 2015 available. I added some scaling presets to the UI.
The Autodesk people who manage the app store have been helpful in getting apps published and updated. Here the store link showing its availability for Revit 2016: https://apps.autodesk.com/RVT/en/Det...windows64%3aen
