API Reference > geometry-core > Curve > GeometryQuery GeometryQuery Class GeometryQuery is an abstract base class with (abstract) methods for querying curve, solid primitive, mesh, and bspline surfaces Extended by BSpline2dNd CoordinateXYZ CurveCollection CurvePrimitive PointString3d Polyface SolidPrimitive Methods Name Description constructor(): GeometryQuery clone(): undefined | GeometryQuery Abstract return a clone cloneTransformed(transform: Transform): undefined | GeometryQuery Abstract return a transformed clone. dispatchToGeometryHandler(handler: GeometryHandler): any Abstract * "double dispatch" call pattern. extendRange(rangeToExtend: Range3d, transform?: Transform): void Abstract extend rangeToExtend by the range of this geometry multiplied by the transform isAlmostEqual(other: GeometryQuery): boolean test for exact structure and nearly identical geometry. isSameGeometryClass(other: GeometryQuery): boolean Abstract test if (other instanceof this.Type). range(transform?: Transform, result?: Range3d): Range3d return the range of the entire (tree) GeometryQuery tryTransformInPlace(transform: Transform): boolean Abstract Attempt to transform in place. tryTranslateInPlace(dx: number, dy: number = 0.0, dz: number = 0.0): boolean try to move the geometry by dx,dy,dz areAlmostEqual(a: undefined | GeometryQuery, b: undefined | GeometryQuery): boolean Static apply instance method isAlmostEqual if both are defined. Properties Name Type Description children Accessor ReadOnly undefined | GeometryQuery[] return GeometryQuery children for recursive queries. geometryCategory AbstractReadonly GeometryQueryCategory Type discriminator.
