API Reference > imodeljs-backend > iModels > IModelImporter > importElementMultiAspects importElementMultiAspects Method Import the collection of ElementMultiAspects into the target iModel. importElementMultiAspects(aspectPropsArray: ElementAspectProps[], filterFunc?: (a: ElementMultiAspect) => boolean): void note For insert vs. update reasons, it is important to process all ElementMultiAspects owned by an Element at once since we don't have aspect-specific provenance. Parameter Type Description aspectPropsArray ElementAspectProps[] The ElementMultiAspects to import filterFunc (a: ElementMultiAspect) => boolean Optional filter func that is used to exclude target ElementMultiAspects that were added during iModel transformation from the update detection logic.
