Learning > backend > Create Element Aspects Edit this page Creating ElementAspects Use IModelDb.Elements.insertAspect to insert a new ElementAspect into an IModelDb. This method takes as its input an ElementAspectProps or a subclass of it, which defines the class and all required properties of the new ElementAspect. The pattern is: const aspectProps = { classFullName: "SomeDomain:SomeAspectClass", element: { id: elementId }, stringProp: "s1", numberProp: 1, }; iModel.elements.insertAspect(aspectProps); Last Updated: 02 February, 2022
