When the distance between the points is greater than 100 kilometers, * the measurement visualization is simplified, and only the horizontal and vertical distances are calculated. * The direct distance option becomes unavailable. * * ![measurement-line-3d](https://developers.arcgis.com/javascript/latest/assets/references/core/widgets/direct-line-measurement-3d.avif) * * When the component is active, a horizontal "laser" line is drawn which indicates the height at the current mouse position. * This line can help in analyzing the heights of objects relative to each other and the terrain. * A second laser line shows the intersection of the scene with the vertical plane that passes through the checkered line. * * **Things to consider** * * * Direct Line Measurement 3D is designed to work in the Scene component. For measurements in the [arcgis-map](https://developers.arcgis.com/javascript/latest/references/map-components/components/arcgis-map/) * component, use [arcgis-distance-measurement-2d](https://developers.arcgis.com/javascript/latest/references/map-components/components/arcgis-distance-measurement-2d/). * * Snapping is enabled by default. This can be temporarily disabled by holding the `CTRL` key. * * Layer types currently supported for snapping are: * [FeatureLayer](https://developers.arcgis.com/javascript/latest/references/core/layers/FeatureLayer/), * [GraphicsLayer](https://developers.arcgis.com/javascript/latest/references/core/layers/GraphicsLayer/) (except Mesh geometries), * [GeoJSONLayer](https://developers.arcgis.com/javascript/latest/references/core/layers/GeoJSONLayer/), * [WFSLayer](https://developers.arcgis.com/javascript/latest/references/core/layers/WFSLayer/), * [CSVLayer](https://developers.arcgis.com/javascript/latest/references/core/layers/CSVLayer/), * [3D Object SceneLayer](https://developers.arcgis.com/javascript/latest/references/core/layers/SceneLayer/), * and [BuildingSceneLayer](https://developers.arcgis.com/javascript/latest/references/core/layers/BuildingSceneLayer/). * * **See also** * * - [DirectLineMeasurementAnalysis](https://developers.arcgis.com/javascript/latest/references/core/analysis/DirectLineMeasurementAnalysis/) * - [Sample - Measurement in 3D](https://developers.arcgis.com/javascript/latest/sample-code/measurement-3d/) * - [Sample - Analysis objects](https://developers.arcgis.com/javascript/latest/sample-code/analysis-objects/) * - [Sample - Color theming for interactive tools](https://developers.arcgis.com/javascript/latest/sample-code/view-theme/) * * @since 4.33 */ export abstract class ArcgisDirectLineMeasurement3d extends LitElement { /** * The [DirectLineMeasurementAnalysis](https://developers.arcgis.com/javascript/latest/references/core/analysis/DirectLineMeasurementAnalysis/) * created or modified by the component. * * When connecting the Direct Line Measurement 3D component to an [arcgis-scene](https://developers.arcgis.com/javascript/latest/references/map-components/components/arcgis-scene/) * component, it automatically creates an empty analysis and adds it to the Scene's * [arcgis-scene.analyses](https://developers.arcgis.com/javascript/latest/references/map-components/components/arcgis-scene/#analyses) collection. * You can then wait for the [DirectLineMeasurementAnalysisView3D](https://developers.arcgis.com/javascript/latest/references/core/views/3d/analysis/DirectLineMeasurementAnalysisView3D/) * to be created before accessing the analysis results. * * ```js * // Get the Scene component and the Direct Line Measurement 3D component, and wait until both are ready. * const viewElement = document.querySelector("arcgis-scene"); * await viewElement.viewOnReady(); * const directLineMeasurement3dElement = document.querySelector("arcgis-direct-line-measurement-3d"); * await directLineMeasurement3dElement.componentOnReady(); * * // Get the DirectLineMeasurementAnalysis created by the Direct Line Measurement 3D component. * const analysis = directLineMeasurement3dElement.analysis; * * // Get the DirectLineMeasurementAnalysisView3D and watch for results. * const analysisView = await viewElement.whenAnalysisView(analysis); * const handle = reactiveUtils.watch( * () => analysisView?.result, * () => { * console.log("Analysis results:", analysisView.result); * }, * ); * ``` * Whenever the component is destroyed, the analysis is automatically removed from the collection. * * Alternatively, a programmatically created [DirectLineMeasurementAnalysis](https://developers.arcgis.com/javascript/latest/references/core/analysis/DirectLineMeasurementAnalysis/) * can be provided to the component. * Then, the application itself needs to add it to and later remove it from the analyses collection of the Scene component. * * ```js * // Create the DirectLineMeasurementAnalysis. * const directLineAnalysis = new DirectLineMeasurementAnalysis({ * startPoint: new Point({ * spatialReference: { latestWkid: 3857, wkid: 102100 }, * x: -13624995.61798748, * y: 4550334.030096778, * z: 63.378210234455764 * }), * endPoint: new Point({ * spatialReference: { latestWkid: 3857, wkid: 102100 }, * x: -13624921.53589075, * y: 4550407.42357004, * z: 63.3783810287714 * }), * }); * // Get the Scene component and the Direct Line Measurement 3D component, and wait until both are ready. * const viewElement = document.querySelector("arcgis-scene"); * await viewElement.viewOnReady(); * const directLineMeasurement3dElement = document.querySelector("arcgis-direct-line-measurement-3d"); * await directLineMeasurement3dElement.componentOnReady(); * * // Add the analysis to the analyses collection of the Scene component. * viewElement.analyses.add(directLineAnalysis); * * // Connect the analysis to the measurement component: * directLineMeasurement3dElement.analysis = directLineAnalysis; * ``` */ accessor analysis: DirectLineMeasurementAnalysis; /** * If true, the component will not be destroyed automatically when it is * disconnected from the document.
