The information on rooms that use the “Floors” and “Ceilings” categories has been incorporated to the data of BIM model in Revit that is exported to Arquimedes. This way Arquimedes can indicate in the comments section of the quantity tables of the room that a specific floor or ceiling is used.
To compose the connects of the quantity lines in the quantity extraction process, having added a job item of the bill of quantities to a type of the BIM model, the “Comments composition” button 
, in the quantities table, must be selected, and add the element “Room” 
to the Category, Family, or Type.
To establish whether an element belongs to a specific room, the element must be defined in or in contact with the correspondent room.
