Since version: 1.5
In the Feature Z profile, expressions can be written to calculate z values for features in a 3D scene or to define the draw order for sorting features in a 2D map view. This is useful in datasets where z information is stored in an attribute instead of the feature's geometry. You can use this profile to return the attribute in lieu of a missing z value. Expressions in this profile must return a Number representing the Z coordinate of the geometry.
Context
This profile was created for use in the following products:
- ArcGIS Maps SDK for JavaScript
- ArcGIS Pro
- ArcGIS Maps SDKs for Native Apps
Spatial reference
The spatial reference of the map in which the expression executes determines the execution context's spatial reference.
Time zone
The time zone of the map in which the expression executes determines the execution context's default time zone.
Profile Variables

Example
The following example gets the geometry of the feature, and adds the value of the HEIGHT
attribute, to create an adjusted height value.
var adjustedHeight = Geometry($feature).z + $feature.HEIGHT;
return adjustedHeight;
