RevitLinkType.CreateFromIFC

Description:
Creates a new Revit link type from an existing Revit file created via import by reference of an asscoiated IFC file.

Remarks:

This function is one of a series of steps necessary for linking an IFC file. To understand how it is used in context, please download the IFC open source code, and look in the Revit.IFC.Import project at Importer.ImportIFC(ImporterIFC importer), under the IFCImportAction.Link branch.

This function regenerates the input document. While the options argument allows specification of a path type, the input path argument must be a full path. Relative vs. absolute determines how Revit will store the path, but it needs a complete path to find the linked document initially.

Document

document

The document in which to create the Revit link.
String

ifcFilePath

The path of the associated IFC file. This must be a full path.
String

revitLinkedFilePath

The path of the existing Revit file that contains elements created via an import by reference operation. This must be a full path.
Boolean

recreateLink

If true, the existing Revit file created via an import by reference operation will be updated based on the information in the IFC file. If false, the existing Revit file will be used as-is.
RevitLinkOptions

options

An options class for loading Revit links.

Return Value LinkLoadResult An object containing the results of creating and loading the Revit link type. It contains the ElementId of the new link.

ArgumentException

document is not a project document. -or- The input path "ifcFilePath" does not represent an IFC file. -or- document already contains a linked model at path revitLinkedFilePath. -or- The document is a cloud model.
ArgumentNullException

A non-optional argument was null
FileAccessException

The model cannot be accessed due to lack of access privileges.
FileArgumentNotFoundException

There is not a valid Revit file at ifcFilePath's location -or- There is not a valid Revit file at revitLinkedFilePath's location
InvalidOperationException

The file is not allowed to access. -or- Revit cannot customize worksets for this model.
ModificationForbiddenException

The document is in failure mode: an operation has failed, and Revit requires the user to either cancel the operation or fix the problem (usually by deleting certain elements). -or- The document is being loaded, or is in the midst of another sensitive process.
ModificationOutsideTransactionException
