	Document^ doc, 
	ICollection<ElementId^>^ partIds
)

Parameters

doc
Type: Autodesk.Revit.DB..::..Document
The document.
partIds
Type: System.Collections.Generic..::..ICollection<(Of <(<'ElementId>)>)>
A set of element ids.

Return Value

An array of clusters such that all the elements in a single cluster are valid for merge. Each cluster will be maximal in that appending any of the other Parts specified as input will result in a collection that is not valid for merge.

Remarks

Element ids in the input set that do not correspond to Part elements will be ignored, as will element ids corresponding to Part elements that already have associated parts.
