BuildingSceneLayer class final

A layer that may be used to visualize building models exported from Building Information Modeling (BIM) projects.

This layer is used to visualize and interact with 3D building models developed using Building Information Modeling tools. The data in a building scene layer may represent building features such as walls, light fixtures, mechanical ductwork, and so forth. This layer is supported when used with ArcGISLocalSceneViewController.

The data in a BuildingSceneLayer is organized into a hierarchy of BuildingSublayer. The sublayers of the building scene layer are a Full Model sublayer, which contains all building components, organized into a hierarchy of sublayers, grouped by discipline (such as Architectural, Mechanical, or Structural). The building scene layer may also contain an Overview sublayer, which may be loaded to display the exterior shell of the building. The Overview sublayer provides a means to quickly visualize a building's exterior, in cases where visualization of interior features is not required. Sublayers are available through LayerContent.subLayerContents.

Due to its complexity, the data in this layer is organized using BuildingGroupSublayer, which contains BuildingComponentSublayer. Often, the building scene layer contains an Overview BuildingComponentSublayer that can be loaded to display the exterior shell of a building. This provides a preview of the entire building without loading all interior features. This layer might also contain a Full Model building group sublayer with all the features in a building grouped by disciplines. Each discipline is a building group sublayer containing building component sublayers with features such as rooftops, walls, doors, AC units, lighting fixtures, columns, or foundations.

Building scene layers always have a SurfacePlacement mode of absolute.

Methods

cancelLoad() → void
Cancels loading metadata for the object.
inherited
clone() → Layer
