bool UpdateFromIFC(
	Document^ document, 
	ExternalResourceReference^ resourceReference, 
	String^ revitLinkedFilePath, 
	bool recreateLink
)

Parameters

document
Type: Autodesk.Revit.DB Document
The document that contains Revit link.
resourceReference
Type: Autodesk.Revit.DB ExternalResourceReference
An external resource reference describing the source of the IFC file used in creation.
revitLinkedFilePath
Type: System String
The path of the Revit file to create to hold the IFC information. This must be a full path.
recreateLink
Type: System Boolean
If true, the Revit file will be updated based on the information in the IFC file. If false, the existing Revit file will be used.

Return Value

Returns true if the update succeeded, false otherwise.

Remarks

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. Note that the IFC file will not be stored directly in the document; it will instead by stored in an intermediate Revit document, whose location is given by revitLinkedFilePath.
