Slice

The SliceAnalysis created or modified by the component.

When connecting the Slice component to the Scene component, it automatically creates an empty analysis and adds it to the Scene's analyses collection. Whenever the component is destroyed, the analysis is automatically removed from the collection.

Alternatively, a programmatically created analysis can be provided to the component. Then, the application itself needs to add it to and later remove it from the Scene's analyses collection.

If true, the component will not be destroyed automatically when it is disconnected from the document. This is useful when you want to move the component to a different place on the page, or temporarily hide it. If this is set, make sure to call the destroy method when you are done to prevent memory leaks.

Attribute

auto-destroy-disabled

Default value

false

Add layers to this collection to exclude them from the slice. Layers that are draped on the ground surface are not affected by this property

Indicates whether the Ground and layers that are draped on the ground surface are excluded from the slice.

Attribute

exclude-ground-surface

Default value

false

Attribute

heading-level

Default value

3

Icon which represents the component. Typically used when the component is controlled by another component (e.g. by the Expand component).

Attribute

icon

Default value

"slice"

The component's default label.

Attribute

label

Replace localized message strings with your own strings.

Note: Individual message keys may change between releases.

Attribute

position

Default value

"bottom-left"

By assigning the id attribute of the Map or Scene component to this property, you can position a child component anywhere in the DOM while still maintaining a connection to the Map or Scene.

Attribute

reference-element

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

Example

// Clone the shape to modify its properties
const shape = slice.shape.clone();
// Set new values for heading and tilt
shape.heading = 180;
shape.tilt = 45;
// Apply the new shape to the slice component's shape
slice.shape = shape;

The component's state. The values mean the following:

• disabled - not ready yet
• ready - ready for slicing
• slicing - currently slicing
• sliced - finished slicing

Attribute

state

Enable tilting the slice shape. If set to true, the slice shape will orient itself as best as possible to the surface under the cursor when first placing the shape. If set to false, the slice shape is restricted to be either horizontal or vertical.

Attribute

tilt-enabled

Default value

false

Emitted when the value of a property is changed. Use this to listen to changes to properties.

Emitted when the component associated with a map or scene view is is ready to be interacted with.

Clear the shape of the slice, effectively removing it from the view. Other properties like excludedLayers and excludeGroundSurface are not modified.

Returns

Promise<void>

Create a promise that resolves once component is fully loaded.

Example

const arcgisSlice = document.querySelector("arcgis-slice");
document.body.append(arcgisSlice);
await arcgisSlice.componentOnReady();
console.log("arcgis-slice is ready to go!");

Returns

Promise<void>

Permanently destroy the component.

Returns

Promise<void>

Start the interactive creation of a new slice, clearing the previous shape.

Returns

Promise<void>
