API Reference > imodeljs-frontend > LocatingElements > SnapDetail SnapDetail Class A SnapDetail is generated from the result of IModelDb.requestSnap call. In addition to the HitDetail about the reason the element was picked, it holds the exact point on the element from the snapping logic, plus additional information that varies with the type of element and snap mode. Extends HitDetail Extended by IntersectDetail Methods Name Description constructor(from: HitDetail, snapMode: SnapMode = SnapMode.Nearest, heat: SnapHeat = SnapHeat.None, snapPoint?: XYZProps): SnapDetail Constructor for SnapDetail. clone(): SnapDetail Make a copy of this SnapDetail. draw(context: DecorateContext): void Draw this HitDetail as a Decoration. getCurvePrimitive(singleSegment: boolean = true): undefined | CurvePrimitive getHitType(): HitDetailType Returns HitDetailType.Snap getPoint(): Point3d Get the snap point if this SnapDetail is hot, the pick point otherwise. setCurvePrimitive(primitive?: CurvePrimitive, localToWorld?: Transform, geomType?: HitGeomType): void Set curve primitive and HitGeometryType for this SnapDetail. setSnapPoint(point: Point3d, heat: SnapHeat): void Change the snap point. Inherited methods Name Inherited from Description getToolTip(): Promise<string | HTMLElement> HitDetail Get the tooltip content for this HitDetail. isSameHit(otherHit?: HitDetail): boolean HitDetail Determine if this HitPoint is from the same source as another HitDetail. Properties Name Type Description adjustedPoint Readonly Point3d AccuSnap/AccuDraw can adjust the point after the snap. geomType undefined | HitGeomType The HitGeomType of this SnapDetail heat SnapHeat isHot Accessor ReadOnly boolean Return true if the pick point was closer than the snap aperture from the generated snap point. isPointAdjusted Accessor ReadOnly boolean Determine whether the SnapDetail.adjustedPoint is different than the SnapDetail.snapPoint. normal undefined | Vector3d Surface normal at snapPoint parentGeomType undefined | HitParentGeomType The HitGeomType of this SnapDetail primitive undefined | CurvePrimitive Curve primitive for snap. snapMode SnapMode snapPoint Readonly Point3d HitPoint adjusted by snap sprite undefined | Sprite A sprite to show the user the type of snap performed Inherited properties Name Type Inherited from Description distFraction Readonly number HitDetail distXY Readonly number HitDetail geometryClass Readonly undefined | GeometryClass HitDetail hitPoint Readonly Point3d HitDetail hitSource Readonly HitSource HitDetail iModel Accessor ReadOnly IModelConnection HitDetail The IModelConnection from which the hit originated. In some cases this may not be the same as the iModel associated with the Viewport -for example, if a TiledGraphicsProvider is used to display graphics from a different iModel in the viewport.This HitDetail's element, subcategory, and model Ids are defined in the context of this IModelConnection. isElementHit Accessor ReadOnly boolean HitDetail Return whether sourceId is for a persistent element and not a pickable decoration. isExternalIModelHit Accessor ReadOnly boolean HitDetail Returns true if this hit originated from an IModelConnection other than the one associated with the Viewport. isMapHit Accessor ReadOnly boolean HitDetail isModelHit Accessor ReadOnly boolean HitDetail modelId Readonly undefined | string HitDetail priority Readonly HitPriority HitDetail sourceId Readonly string HitDetail subCategoryId Readonly undefined | string HitDetail testPoint Readonly Point3d HitDetail viewport Readonly ScreenViewport HitDetail Defined in core/frontend/src/HitDetail.ts Line 185 Last Updated: 29 November, 2022
