SliceAnalysis can be used to programmatically create a plane that slices through 3D features in a 3D SceneView. A slice takes a SlicePlane as an input, which can be set through the shape property. If the shape has a tilt angle other than 0, the angle is only considered if the tiltEnabled property is set to true.

const analysis = new SliceAnalysis({
  shape: {
    type: "plane", // autocasts as new SlicePlane()
    position: {
      type: "point",
      x: -0.1,
      y: 51.5
    },
    width: 50,
    height: 50,
    tilt: 45
  },
  tiltEnabled: true
});

view.analyses.add(slice);

SceneView.analyses can contain multiple slice analyses, but only one of these analyses can be active at a time. When working with multiple slices, set the active property of a slice view to true to occlude the parts of the 3D features that are in front of the slice plane. When a slice view is activated, all other slice views are automatically deactivated.

view.whenAnalysisView(slice).then((sliceView) => {
  sliceView.active = true;
});

To place the slice interactively in the view using positioning, scaling and rotation handles, it is recommended to use the Slice widget.

Property Overview

Any properties can be set, retrieved or listened to. See the Working with Properties topic.
Show inherited properties Hide inherited properties
Name Type Summary Class
String

The name of the class.

Accessor
SlicePlane

The shape used to slice elements in a 3D scene.

SliceAnalysis
Boolean

Whether the shape supports a tilt angle or not.

SliceAnalysis
String For SliceAnalysis the type is always "slice". SliceAnalysis

Property Details

declaredClass Stringreadonly inherited

The name of the class. The declared class name is formatted as esri.folder.className.

The shape used to slice elements in a 3D scene. Currently the only supported shape is a plane.

tiltEnabled Boolean

Whether the shape supports a tilt angle or not. If set to true, the SlicePlane.tilt angle is respected. By default it is set to false, so the tilt value of the shape is not taken into consideration.

Default Value:true

type Stringreadonly

For SliceAnalysis the type is always "slice".

Method Overview

Name Return Type Summary Class

Adds one or more handles which are to be tied to the lifecycle of the object.

Accessor

Method Details

addHandles(handleOrHandles, groupKey)inherited

Since: ArcGIS Maps SDK for JavaScript 4.25 Accessor since 4.0, addHandles added at 4.25.

Adds one or more handles which are to be tied to the lifecycle of the object. The handles will be removed when the object is destroyed.

// Manually manage handles
const handle = reactiveUtils.when(
  () => !view.updating,
  () => {
    wkidSelect.disabled = false;
  },
  { once: true }
);

this.addHandles(handle);

// Destroy the object
this.destroy();
Parameters
handleOrHandles WatchHandle|WatchHandle[]

Handles marked for removal once the object is destroyed.

groupKey *
optional

Key identifying the group to which the handles should be added. All the handles in the group can later be removed with Accessor.removeHandles(). If no key is provided the handles are added to a default group.

clone(){this}

Creates a deep clone of this object. Any properties that store values by reference will be assigned copies of the referenced values on the cloned instance.

Returns
Type Description
this A deep clone of the class instance that invoked this method.

hasHandles(groupKey){Boolean}inherited

Since: ArcGIS Maps SDK for JavaScript 4.25 Accessor since 4.0, hasHandles added at 4.25.

Returns true if a named group of handles exist.

Parameter
groupKey *
optional

A group key.

Returns
Type Description
Boolean Returns true if a named group of handles exist.
Example
// Remove a named group of handles if they exist.
if (obj.hasHandles("watch-view-updates")) {
  obj.removeHandles("watch-view-updates");
}

removeHandles(groupKey)inherited

Since: ArcGIS Maps SDK for JavaScript 4.25 Accessor since 4.0, removeHandles added at 4.25.

Removes a group of handles owned by the object.

Parameter
groupKey *
optional

A group key or an array or collection of group keys to remove.

Example
obj.removeHandles(); // removes handles from default group

obj.removeHandles("handle-group");
obj.removeHandles("other-handle-group");
