Compare and update Instance / Occurrence in one Room/ Space

By linking Rooms/Spaces and Family Types in Revit with the corresponding Rooms and Items in dRofus, you can verify and compare the number of Occurrences of Items within a selected Room (or Space) in Revit using the "Items in Room" Panel. This panel presents a side-by-side comparison of the number of Items in the dRofus Room and the number of Items in the Revit Room. This process helps to ensure that the correct number of Items planned in dRofus accurately populates the Room in Revit.
