Every project has a live view in which you can work with your project as usual, for example making measurements, adding annotations, run a point cloud analysis, create a PDF report, and so on.
However, every project also has a draft view in which you can register scans and clusters, make adjustments to registration after adding new scans, import more scans and so on. The changes in this draft view are only be visible to other users after you have published them.
To toggle between live and draft view, click Live or Draft at the top of the screen.
NOTE: At a first glance the live and draft view may look similar, also depending on your view settings. Always make sure you are working in the correct view.
