It is possible to mark the elements that the user does not want to measure in a given item. This tool supplements other existing tools to filter and define what will be measured. The possibility to mark elements to avoid quantities is available once a Revit element has been linked to an item and the appropriate extraction combination has been selected or created. In the quantities detail table that is created, the user can mark the elements of each line that they do not want to measure by means of a selection box located at the beginning of each quantities detail line.
