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

This method marks the end of a link instance being exported.

This method marks a change of the material.

This method is called when a Polyline is being output.
