## Constructors

`LoadSubtreeConfig.``constructor`()
  LoadSubtreeConfig(): `LoadSubtreeConfig`

  Returns: `LoadSubtreeConfig`

## Properties

`LoadSubtreeConfig.``additionalMatrix`
  additionalMatrix: (None | `Matrix`)

  Optional matrix to get multiplied into the net attachment matrix.

`LoadSubtreeConfig.``allowMissingExternalModels`
  allowMissingExternalModels: boolean

  Controls whether or not missing models are ignored or cause an error.

`LoadSubtreeConfig.``attachInvisibly`
  attachInvisibly: boolean

  If true, then models are attached with all geometry turned invisible. If exist, default CAD configuration and CAD view will not be activated.

`LoadSubtreeConfig.``ignoreBimRelationships`
  ignoreBimRelationships: boolean

  If true BIM relationships will not be loaded. This can reduce memory consumption

`LoadSubtreeConfig.``ignoreCadViews`
  ignoreCadViews: boolean

  If true CAD views will not be loaded. This can reduce memory consumption

`LoadSubtreeConfig.``ignoreFilters`
  ignoreFilters: boolean

  If true filters will not be loaded. This can reduce memory consumption

`LoadSubtreeConfig.``ignoreGenericTypes`
  ignoreGenericTypes: boolean

  If true generic types (IFC types) will not be loaded. This can reduce memory consumption

`LoadSubtreeConfig.``ignoreLayers`
  ignoreLayers: boolean

  If true layers will not be loaded. This can reduce memory consumption

`LoadSubtreeConfig.``implicitlyLoadXmlExternalModels`
  implicitlyLoadXmlExternalModels: boolean

  If true, then external models found in XML files will be implicitly loaded. Otherwise [[Model.requestNodes]] must be called to load the external models.

## Methods

`LoadSubtreeConfig.``copy`()
  copy(): `LoadSubtreeConfig`

  Returns: `LoadSubtreeConfig`
