I think there should be another synchronize option for working with cloud models. The ability to abandon all changes and reload the latest model would be very helpful when working with live models when referencing. I sketch frequently on the revit model to design and detail, and these are not meant to be permanent/ visible changes, just temporary marks. When its time to actually update the model, I either have to undo all of my changes one by one, or close and reopen the model, to ensure that none of my temporary sketching accidentally gets uploaded to the live model. If I could just abando all changes with the click of a button to ensure a clean model and sync, that would be great.
