Move occurrence and systems to this model is explained in detail via Split model and Update Model Name on Occurrences
Include physical connectors supports, including all the detailed pieces that make up a system, for example, elbows, fittings, cables, etc.

The current item and occurrence configurations being used are referenced here.
There can be several changes when syncing systems and system components, so an additional log folder is mapped to capture each and every time a sync is completed.
Categories shows a list of Revit categories that will be included when syncing occurrences. This can be helpful to limit the occurrences that need to be import or synced to specific Revit categories.
Group occurrences by category is used to group occurrences by specific Revit categories. This can be helpful to group several occurrences into a single occurrence with the quantity of instances based on the shared Revit categories defined.
