I've just finished the registration of 2 buildings that are quite close to each other, but my surveyors didn't collect enough intermittent scans in between the buildings to accurately combine the 2 groups. It would be useful to just select a group and create a new project from that data to take straight through to indexing. Unfortunately I had to duplicate the project, disband a group in each project, then delete the scans 1 at a time in the import screens before I could index. I beleive this would provide a very fast workflow; if one person is registering they could easily keep feeding info to the Revit (or other) guys as various groups are registered.
Obviously the group would need removing from the previous project - or at least an option to do so.
