IExportContextBase Interface

IExport Context Base Interface

An interface that as common base for IModelExportContext and IExportContext2D.

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 25.0.0.0 (25.0.0.0)
Syntax 
public interface IExportContextBase : IExportContext

The IExportContextBase type exposes the following members.

Methods
Name Description
Public method 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 )
Public method IsCanceled This method is queried at the beginning of every element.
(Inherited from IExportContext )
Public method OnCurve This method is called when a Curve is being output.
Public method Code example OnElementBegin This method marks the beginning of an element to be exported.
(Inherited from IExportContext )
Public method OnElementEnd This method marks the end of an element being exported.
(Inherited from IExportContext )
Public method Code example OnFaceBegin This method marks the beginning of a Face to be exported.
(Inherited from IExportContext )
Public method OnFaceEnd This method marks the end of the current face being exported.
(Inherited from IExportContext )
Public method Code example OnInstanceBegin This method marks the start of processing of an instance node (e.g. a family instance).
(Inherited from IExportContext )
Public method OnInstanceEnd This method marks the end of processing of an Instance Node (e.g. a family instance).
(Inherited from IExportContext )
Public method Code example OnLight This method marks the beginning of export of a light which is enabled for rendering.
(Inherited from IExportContext )
Public method 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

Public method Code example OnLinkBegin This method marks the beginning of a link instance to be exported.
(Inherited from IExportContext )
Public method OnLinkEnd This method marks the end of a link instance being exported.
(Inherited from IExportContext )
Public method Code example OnMaterial This method marks a change of the material.
(Inherited from IExportContext )
Public method OnPolyline This method is called when a Polyline is being output.
Public method 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

Public method Code example OnPolymesh This method is called when a tessellated polymesh of a 3d face is being output.
(Inherited from IExportContext )
Public method OnRPC This method marks the beginning of export of an RPC object.
(Inherited from IExportContext )
Public method OnText This method is called when a text annotation object is being output.
Public method Code example OnViewBegin This method marks the beginning of a 3D view to be exported.
(Inherited from IExportContext )
Public method OnViewEnd This method marks the end of a 3D view being exported.
(Inherited from IExportContext )
Public method Code example 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 )
