Radar stores the reports created after every saving or synchronization in two folders:
The Radar dashboard includes the Open Profile Folder button that opens directly the Main Folder where the reports of the Revit models are being saved. From there, the Archive Folder is also accesible, without having to manually browse in the folders.
In the Project Report dashboard it is also possible to access reports from previous dates by clicking on the Report Selection button. Be aware, that if in this option a former report is selected, when going back to the Comparison Report dashboard, it will not be shown this report, but the latest report generated from that Revit model.
