Parameters

folder
Type: SystemString
Output folder into which the file will be exported. The folder must exist.
name
Type: SystemString
Either the name of a single file or a prefix for a set of files. If empty, automatic naming will be used.
options
Type: Autodesk.Revit.DBIFCExportOptions
Various options applicable to the IFC format. If a null reference (Nothing in Visual Basic), all options will be set to their respective default values.

Return Value

True if successful, otherwise False.

Remarks

Exporting to IFC requires that document is modifiable, therefore there must be a transaction already open when this method is called.

This method may not be invoked during dynamic update, for the internal routine might need to modify the existing transaction.
