After drawings from review and project folders are matched automatically, some of the drawings are still identified as unmatched even though these drawings in question share the same name.
The drawing names may be the same, but the individual drawing internal IDs are different. This can occur, for example, when a drawing is W-blocked into a new drawing. Different drawing internal IDs are also assigned to AutoCAD Architecture 2022 toolset or Revit Architecture drawings when they are exported to AutoCAD.
