We need to see a report that shows the status of acquired data. The ability to set the status of a tag to ignore will be required for the aggregation report to be useful. For instance, P&ID segments should be ignored as they are not tagged items but we need to aggregate the 3D segment to P&ID so that should be reported (when we have the ability to aggregate segments).
There are also a lot of supplemental objects in the 3D model that do not require aggregation but will report as unaggregated if not set to ignore.
Using the "reject" option in Aggregation and publishing that sets the object to "ignored"
Using the "Export" option will provide all of the aggregation information in an Excel Sheet
