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)
