This event is raised when Revit is just about to export a view of the document. It is raised only during accelerated export jobs, in which views are exported in parallel using a background process. Accelerated export only occurs when exporting to DWF formats and not combining views into a single file.

Handlers of this event are permitted to make modifications to any document (including the active document), except for documents that are currently in read-only mode.

Event is not cancellable. The 'Cancellable' property of event's argument is always False.

The following API functions are not available for the current document during this event:

• All overloads of Autodesk.Revit.DB.Document.Export()
• Autodesk.Revit.DB.Document.Print()
• Print and similar overloads.
• SubmitPrint and similar overloads.
• [!:Autodesk::Revit::DB::Document::Close()] and similar overloads.
• [!:Autodesk::Revit::DB::Document::Save()] .
• [!:Autodesk::Revit::DB::Document::SaveAs(String)] and similar overloads.
