Quantity filters allow users to obtain the quantities of job items that are only assigned to phases, categories, levels or assignments (entity–job item) of Revit and are to be measured. Two types of filters can be established:
- Global filters (categories, phases and levels)
Global filters are created using the Quantity filters option in the drop-down menu that appears when the button of the “Job item assignment and quantity extraction” dialogue box is pressed. - Filters by assignment (entity – job item)
Filters by assignment allow users to obtain quantities only from elements that meet specific requirements. Filters created by assigning job items to entities are saved by categories. Filters of this type are created based on the element parameters.
Once a job item has been assigned to a Revit entity or vice-versa, filters can be carried out by assignments. If, for example, users wish to filter elements whose length is less than 12 m, they must first press the button and, in the “Select a filter to limit the elements to be measured” dialogue box, add the filter.
