Type: Autodesk.Revit.DB View
View used to aid placement of the imported file. If the options specify ThisViewOnly, this argument is required and the imported file will only be visible in the specified view. If the options specify center-to-center placement, this argument is required and the imported file will be placed in the center of the specified view. Otherwise, this view is used to obtain a base level to associate with the imported file. If not specified, an existing view will be chosen instead and may open a view or associate the imported file to an arbitrary level.

The id of imported instance after a successful import.
