Parameters

document Document: The document containing the global parameters

Return Value

ISet ElementId
A collection of Element Ids of global parameter elements.

Exceptions

Exception	Condition
ArgumentException	Global parameters are not supported in the given document. A possible cause is that it is not a project document, for global parameters are not supported in Revit families.
