Style layers in a scene

In Layer style , you can explore layers through smart mapping styles and discover themes and patterns in the data. For example, you can visualize average income levels in communities with continuous colors and sizes. You can change styles for point, line, polygon, 3D object, and point cloud layers.

To style a layer, complete the following steps:

1. Verify that you are signed in to your account and open Scene Viewer.
2. On the Designer toolbar, click Layer Manager to open the Layer Manager pane.
3. Click the layer name or Options and select Layer style to open a layer.
4. Under Choose main attribute to visualize, choose one of the following options to determine which styles are available in the style gallery:
   • No attribute—Styles that have a constant color or size are available, such as 2D Marker or 3D extrusion.
   • Expression—Styles that use colors or sizes based on an expression are available, such as the Counts and Amounts and Type styles.
     • Click Create expression to open a window to create an Arcade expression.
     • Provide a title for the new expression at the top.
     • Create a custom expression in the editor.
     • After the expression is created, click Edit to edit the expression.

   • Attributes—Styles that use colors or sizes based on an attribute in the list are available, such as the Counts and Amounts and Type styles.

   The available styles in the gallery depend on the layer type, such as point, 3D object, or point cloud layers.

5. Under Choose a drawing style, choose the style to use:
   1. Click Select to apply the style to the layer in the scene.
   2. Click Options to open the style.
6. Style the layer.

   See the individual layer style workflows, such as Style point layers or Style 3D object layers, for details on the options for styling the layer.

7. On the Designer toolbar, click Save to save the style changes to the scene.

Styling considerations

Keep the following in mind when styling a layer:

• Scene Viewer doesn't allow modifying styles when layers have numerical data and were previously styled with classified graduated symbols or classified graduated colors.
• When sharing a web layer, ArcGIS Pro uses Cartographic Information Model (CIM) symbols by default, which are not supported in Scene Viewer. To ensure the layer style is supported, you must check the Use symbol types compatible with all clients check box under the Configurations tab.
• Not all styles are available for each attribute. In many cases, Scene Viewer identifies one of the drawing styles by default based on the nature of the data in the layer, and the style automatically is applied in the scene.
• Styling with attributes is not available with point cloud layers.
