Show labels on layer in 3D

Display custom labels in a 3D scene.

Use case

Labeling features is useful to visually display information or attributes on a scene. For example, city officials or maintenance crews may want to show installation dates of features of a gas network.

How to use the sample

Pan and zoom to explore the scene. Notice the labels showing installation dates of features in the 3D gas network.

How it works

1. Create a scene from a PortalItem.
2. Add the scene to a SceneView and load it.
3. After loading is complete, obtain the FeatureLayer from one of the GroupLayers in the scene’s operational layers.
4. Create a TextSymbol to use for displaying the label text.
5. Create a LabelDefinition using an ArcadeLabelExpression.
6. Add the definition to the feature layer with featureLayer.addLabelDefinition(labelDefinition).
7. Lastly, enable labels on the layer using featureLayer.labelsAreEnabled.
