IExportContextBase Interface

An interface that as common base for IModelExportContext and IExportContext2D.

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 25.3.0.0 (25.3.0.0)

Syntax

public interface IExportContextBase : IExportContext

Public Interface IExportContextBase
	Inherits IExportContext

public interface class IExportContextBase : IExportContext

type IExportContextBase = 
    interface
        interface IExportContext
    end

The IExportContextBase type exposes the following members.

Methods

	Name	Description
	Finish	This method is called at the very end of the export process, after all entities were processed (or after the process was cancelled). (Inherited from IExportContext)
	IsCanceled	This method is queried at the beginning of every element. (Inherited from IExportContext)
	OnCurve	This method is called when a Curve is being output.
	OnElementBegin	This method marks the beginning of an element to be exported. (Inherited from IExportContext)
	OnElementEnd	This method marks the end of an element being exported. (Inherited from IExportContext)
	OnFaceBegin	This method marks the beginning of a Face to be exported. (Inherited from IExportContext)
	OnFaceEnd	This method marks the end of the current face being exported. (Inherited from IExportContext)
	OnInstanceBegin	This method marks the start of processing of an instance node (e.g. a family instance). (Inherited from IExportContext)
	OnInstanceEnd	This method marks the end of processing of an Instance Node (e.g. a family instance). (Inherited from IExportContext)
	OnLight	This method marks the beginning of export of a light which is enabled for rendering. (Inherited from IExportContext)
	OnLineSegment	This method is called after unhandled curve was tessellated to line segments and sent to the output. Note for 2D export: if the export is performed for the view in non-Wireframe display style, then this method is called outside of view, instance and link begin/end calls but still between OnElementBegin2D/OnElementEnd2D calls this method is never called for annotation elements, i.e. their geometry should be processed in methods OnCurve and OnPolyline
	OnLinkBegin	This method marks the beginning of a link instance to be exported. (Inherited from IExportContext)
	OnLinkEnd	This method marks the end of a link instance being exported. (Inherited from IExportContext)
	OnMaterial	This method marks a change of the material. (Inherited from IExportContext)
	OnPolyline	This method is called when a Polyline is being output.
	OnPolylineSegments	This method is called after unhandled curve was tessellated to polyline segments and sent to the output. Note for 2D export: if the export is performed for the view in non-Wireframe display style, then this method is called outside of view, instance and link begin/end calls but still between OnElementBegin2D/OnElementEnd2D calls this method is never called for annotation elements, i.e. their geometry should be processed in methods OnCurve and OnPolyline
	OnPolymesh	This method is called when a tessellated polymesh of a 3d face is being output. (Inherited from IExportContext)
	OnRPC	This method marks the beginning of export of an RPC object. (Inherited from IExportContext)
	OnText	This method is called when a text annotation object is being output.
	OnViewBegin	This method marks the beginning of a 3D view to be exported. (Inherited from IExportContext)
	OnViewEnd	This method marks the end of a 3D view being exported. (Inherited from IExportContext)
	Start	This method is called at the very start of the export process, still before the first entity of the model was send out. (Inherited from IExportContext)
