SliceAnalysis | API Reference | ArcGIS Maps SDK for JavaScript 4.31

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 sliceAnalysis = 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(sliceAnalysis);

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 analysis view to true to occlude the parts of the 3D features that are in front of the slice plane. When a slice analysis view is activated, all other slice analysis views are automatically deactivated.

view.whenAnalysisView(sliceAnalysis).then((sliceAnalysisView) => {
  sliceAnalysisView.active = true;
});

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

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 Inherited Property declaredClass Stringreadonly Inherited from Accessor

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

shape Property shape SlicePlaneautocast

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

tiltEnabled Property 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 Property type Stringreadonly

For SliceAnalysis the type is always "slice".

Return Type	Summary	Class
	Adds one or more handles which are to be tied to the lifecycle of the object.	Accessor
this	Creates a deep clone of this object.	SliceAnalysis
Boolean	Returns true if a named group of handles exist.	Accessor
	Removes a group of handles owned by the object.	Accessor

Method Details

addHandles Inherited Method addHandles(handleOrHandles, groupKey) Inherited from Accessor 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 Method 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 Inherited Method hasHandles(groupKey){Boolean} Inherited from Accessor 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 Inherited Method removeHandles(groupKey) Inherited from Accessor 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");
