API Reference > imodeljs-common > Geometry > GeometryStreamBuilder > appendGeometryRanges appendGeometryRanges Method Store local ranges in GeometryStream for all subsequent geometry appended. Can improve performance of range testing for elements with a GeometryStream containing more than one GeometryQuery differentiable by range. Not useful for a single GeometryQuery as its range and that of the GeometricElement are the same. Ignored when defining a GeometryPart and not needed when only appending GeometryPart instances to a GeometricElement as these store their own range. appendGeometryRanges(): void Returns - void Defined in core/common/src/geometry/GeometryStream.ts Line 223 Last Updated: 12 June, 2024
