ExporterIFC

Description:
The main class provided by Revit to allow implementation of IFC export.

Remarks:
An instance of this class is provided to clients which implement IExporterIFC in order to provide an implementation for IFC export. It contains information on the options selected by the user for the export operation, as well as members used to access specific types of data needed to implement the export properly.

Name	Return Type	Description
M AddBuildingStorey(ElementId, IFCLevelInfo)	None	Adds building storey to the exporter's internal cache.
M ClearFaceWithElementHandleMap()	None	Clear face with element handle map.
M Dispose()	None	Releases all resources used by the
M FindSpaceBoundingElementHandle(ElementId, ElementId)	IFCAnyHandle	Looks up the handle associated to the element and level id from the ExporterIFC's internal cache.
M Get2DContextHandle()	The IfcRepresentationContext.	Obtains the IfcRepresentationContext handle to be used for 2D entities (Annotations).
M Get3DContextHandle(String)	IFCAnyHandle	Obtains the IfcRepresentationContext or IfcRepresentationSubContext handle to be used for 3D entities (Model entities).
M GetDoorWindowOpeningHandle(ElementId)	The opening handle.	Get the handle to the opening associated with a hosted (door/window) element from the internal cache.
M GetFamilyName()	The family name.	Gets the name of the element assigned to the current export state.
M GetFile()	IFCFile	Gets the handle to the IFC file being created during this export operation.
M GetHostObjects()	IList	Returns a collection containing the host object handles in the document.
M GetLayerNameForPresentationLayer(Element, ElementId)	The layer name.	Get the layer name associated with an element from the default layer mapping table.
M GetLevelInfo(ElementId)	The level information.	Returns an object representing the information about a level in the document.
M GetLevelInfos()	IDictionary	Returns a collection containing the information about all levels in the document.
M GetMaterialIdForCurrentExportState()	The material id.	This gets the material id that is associated with the element in the current export state.
M GetOptions()	IDictionary	Gets the collection of named options set by the exporter client.
M GetOrCreateFillPattern(ElementId, Color, Double)	The IfcSurfaceStyle.	Get (or create) the IfcFillPatternStyle associated with an ElementId.
M GetPresentationLayerAssignments()	The map.	Get the list of the internally IfcPresentationLayerAssignments and their respective shape representations.
M GetRelatedElements()	ICollection<IFCAnyHandle>	Gets all elements not associated to stories.
M GetRelatedProducts()	ICollection<IFCAnyHandle>	Gets all products not associated to stories.
M PopExportState()	None	Resets the internal state of the exporter to process the previously active input element (if any), or the default state if the stack is empty.
M PopTransform()	None	Resets the internal transform of the exporter to process the previously active input element (if any), or the default transform if the stack is empty.
M PushExportState(Element, GeometryElement)	None	Sets the internal state of the exporter to process the geometry and properties of the input element.
M PushTransform(Transform)	None	Sets the internal transform of the exporter to process the geometry and properties of the input element.
M RegisterDoorWindowForUncreatedOpening(ElementId, IFCAnyHandle)	None	Registers a door or window in the ExporterIFC's internal cache. The ids registered correspond to openings in walls which have not been processed and created yet.
M RegisterFaceWithElementHandle(Face, IFCAnyHandle)	None	Register face with element handle to make sure the openings created are related to the right element.
M RegisterShapeForPresentationLayer(Element, ElementId, IFCAnyHandle)	None	Sets an IfcShapeRepresentation to be used for the IfcPresentationLayerAssignment associated with the given Revit category and element.
M RegisterSpaceBoundingElementHandle(IFCAnyHandle, ElementId, ElementId)	None	Stores a handle representing a space bounding element to the ExporterIFC's internal cache.
M RemoveBuildingStorey(ElementId)	None	Removes an IFCLevelInfo corresponding to a level from the exporter's internal cache.
M Set2DContextHandle(IFCAnyHandle)	None	Sets the IfcRepresentationContext handle to be used for 2D entities (Annotations).
M Set3DContextHandle(IFCAnyHandle, String)	None	Sets the IfcRepresentationContext or IfcRepresentationSubContext handle to be used for 3D entities (Model entities).
M SetFile(IFCFile)	None	Sets the handle to the IFC file being created during this export operation.
M SetMaterialIdForCurrentExportState(ElementId)	None	This sets the material id that is to be associated with the element in the current export state.
M SetOwnerHistoryHandle(IFCAnyHandle)	None	Sets the handle to the IfcOwnerHistory for the file.
