Properties

publicreadonlyclasses

classes: BimIfcClass[] = []

All BimIfcClass instances referenced by BimProduct‘s in the IFC file this instance represents.

publicreadonlydiscipline

discipline: Discipline

The discipline of the IFC file this instance represents.

publicreadonlyfloors

floors: BimIfcBuildingStorey[] = []

All IfcBuildingStorey (BimIfcBuildingStorey) instances in the IFC file this instance represents.

publicreadonlyifcHttpResource

ifcHttpResource: BimChangeIfc

publicreadonlyifcName

ifcName: string

The name of the IFC file this instance represents.

publicreadonlyindex

index: BimIfcIndex

The IFC index (.idx file) of the IFC file this instance represents. This describes (in a very raw format) the content of the IFC file. It does not include any geometry or property sets.

publicoptionalreadonlyloadOptions

loadOptions?: BimApiIfcObjectsLoadOptions

The BimApiIfcObjectsLoadOptions options (if any) that was used when this instance was created.

publicreadonlyloader

loader: BimIfcLoaderElementParent

The loader this instance belongs to.

publicreadonlymaterials

materials: Materials

Reference to a Materials instance.

publicreadonlymeshCount

meshCount: number

The total number of BimProductMesh instances in the IFC file this instance represents. Same as ifcProductsWithGeometryCount.

publicreadonlyproducts

products: BimIfcObject[] = []

All IFC products in the IFC file this instance represents. Here represented as a flat list.

publicreadonlyproject

project: BimIfcObject

The IfcProject instance of the IFC file this instance represents.

publicreadonlyspaces

spaces: BimIfcSpace[] = []

All IfcSpace (BimIfcSpace) instances in the IFC file this instance represents.

publicreadonlystyles

styles: BimIfcStyle[] = []

All IFC styles that the BimProductMesh instances in the IFC file refers to. The styles are used to color the meshes.

publicoptionalreadonlytransform

transform?: Matrix

An optional transform for the IFC file. This transform will be applied to all IFC product geometries

publicreadonlytransformsRepository

transformsRepository: BimTransformsRepository

Reference to the transform repository this instance uses when transforming IFC product geometries.

publicreadonlytypeObjectRepository

typeObjectRepository: BimTypeObjectRepository

Reference to the type object repository this instance uses for type properties.

Accessors

  • The IFC change (file) this instance represents.

    Returns BimChangeIfc

publicifcProductsWithGeometryCount

  • get ifcProductsWithGeometryCount(): number

  • The total number of BimProductMesh instances in the IFC file this instance represents. Same as meshCount.

Methods

publicensureVertexDataLoaded

  • ensureVertexDataLoaded(): Promise<boolean>

  • Ensures that the vertex data is loaded.

    Returns Promise<boolean>

    A promise that resolves to a boolean. See it as a signal. I will be true if the call actualy loaded the data. Otherwhise it will be false (data loading is either in progress or has completed).

publicgetVertexData

  • Gets the vertex data for a given product mesh descriptor.

    Parameters

    Returns BimVertexData

    The vertex data.

publicloadPropertySets

  • loadPropertySets(clearCache?: boolean): Promise<boolean>

  • Loads the property sets and assigns them to the IFC products contained within this instance.

    Parameters

    • clearCache: boolean = false

    Returns Promise<boolean>

    A promise that resolves to a boolean indicating whether the property set was loade

publicwriteVertexData

  • writeVertexData(ifcProductMesh: BimProductMesh, transform: FastTransform, destination: GeometryArrays, offset: GeometryArrayOffset, aabb: { max: Vector3; min: Vector3 }, options: { includeNormals?: boolean }): void

  • Writes the vertex data to the specified destination.

    Parameters

    • ifcProductMesh: BimProductMesh

      The IFC product mesh.

    • transform: FastTransform

      The transformation matrix.

    • destination: GeometryArrays

      The destination geometry arrays.

    • offset: GeometryArrayOffset

      The offset in the geometry arrays.

    • aabb: { max: Vector3; min: Vector3 }

      The axis-aligned bounding box.

    • options: { includeNormals?: boolean }
