Both are described below. * * It is also possible to toggle snapping by pressing and holding down the `CTRL` key. This toggles the snapping on/off. * * #### Self snapping (Geometry guides) * Self snapping is set via the [selfEnabled](https://developers.arcgis.com/javascript/latest/references/core/views/interactive/snapping/SnappingOptions/#selfEnabled) property. This means that while a user is actively creating or updating a feature or graphic, they will see visualizations to help identify perpendicular and parallel lines, in addition to visualizations which aid in snapping to an extension of an existing feature. The following briefly demonstrates what self snapping looks like in a 2D application. Although this is shown for 2D, the same premise applies for 3D as well. * * ![self-snapping](https://developers.arcgis.com/javascript/latest/assets/references/core/widgets/sketch/snapping-self-2d.gif) * #### Feature snapping * Feature snapping is set via the [featureEnabled](https://developers.arcgis.com/javascript/latest/references/core/views/interactive/snapping/SnappingOptions/#featureEnabled) property. It provides the ability to snap vertices of a graphic or feature that is currently being drawn or reshaped to that of an existing feature's vertex, edge, or end point. These existing features belong to layers within the [Map](https://developers.arcgis.com/javascript/latest/references/core/Map/) and must be specified in the [featureSources](https://developers.arcgis.com/javascript/latest/references/core/views/interactive/snapping/SnappingOptions/#featureSources) property. The following two images demonstrate feature snapping in a 2D application. Similar to self snapping, the same premise applies for 3D as well. * * ![feature-snapping-create](https://developers.arcgis.com/javascript/latest/assets/references/core/widgets/sketch/snapping-feature-2d.gif) * * The above shows feature snapping to an existing feature's vertex endpoint and edge while creating a new feature. The bottom demonstrates taking an existing feature and reshaping its geometry to snap to another feature's vertex points. * * ![feature-snapping-update](https://developers.arcgis.com/javascript/latest/assets/references/core/widgets/sketch/snapping-reshape-2d.gif) * * > [!WARNING] * > * > **Things to consider:** * > 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/), * > [MapNotesLayer](https://developers.arcgis.com/javascript/latest/references/core/layers/MapNotesLayer/) (2D only), [3D Object SceneLayer](https://developers.arcgis.com/javascript/latest/references/core/layers/SceneLayer/) (3D only), and * > [BuildingSceneLayer](https://developers.arcgis.com/javascript/latest/references/core/layers/BuildingSceneLayer/) (3D only). * > Snapping is not yet implemented when using the [Sketch widget's](https://developers.arcgis.com/javascript/latest/references/core/widgets/Sketch/) circle tool.

However, snapping can still be activated by setting the [enabled](https://developers.arcgis.com/javascript/latest/references/core/views/interactive/snapping/SnappingOptions/#enabled) property to `true` in the [Sketch widget](https://developers.arcgis.com/javascript/latest/references/core/widgets/Sketch/) or its [view model](https://developers.arcgis.com/javascript/latest/references/core/widgets/Sketch/SketchViewModel/). *Note that this enables snapping for all tools.
