Filter and return Revit elements inside a bounding box. BoundingBox.GetElementsInside exposes Revits ElementQuickFilter class, which operates only on the ElementRecord (a low-memory class), making it ideal for rapid element containment testing and collection. Note that the results are – by design – coarse, as the input element Outlines (BoundingBoxes) are used to determine the result, not the geometry. QuickFilters therefore, should be used as a means of optimisation prior to performing more complex, time-consuming processes, such as geometry intersections.
For example, these nodes can be used to optimise an interference checking workflow by collecting only elements within the proximity of another element. The result will be a far more focused collection of elements, making any subsequent geometry or element interference process significantly more efficient as redundant interference tests will be largely eliminated.
The optional tolerance input can be used to collect elements extending from the BoundingBox by the distance input. Use positive values to increase the BoundingBox zone, or negative values to decrease the zone. It uses the active document units (mm, cm, m etc) and converts them to Revit internal units dynamically.
