Parameters

file
Type: SystemString
Full path of the file to link. File must exist and must be a valid DGN file.
options
Type: Autodesk.Revit.DBDGNImportOptions
Various import options applicable to the DGN format. If a null reference (Nothing in Visual Basic), all options will be set to their respective default values.
pDBView
Type: Autodesk.Revit.DBView
View used to aid placement of the linked file. If the options specify ThisViewOnly, this argument is required and the linked file will only be visible in the specified view. If the options specify center-to-center placement, this argument is required and the linked 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 linked file. If not specified, an existing view will be chosen instead and may open a view or associate the linked file to an arbitrary level.
elementId
Type: Autodesk.Revit.DBElementId%
The id of linked instance after a successful link.

Return Value

True if successful, otherwise False.

Remarks

Link isn't supported for family documents. Please use import instead.
