Syntax

C#
`public static FlexDuct Create( Document document, ElementId systemTypeId, ElementId ductTypeId, ElementId levelId, IList<XYZ> points )`

Visual Basic
`Public Shared Function Create ( _ document As Document, _ systemTypeId As ElementId, _ ductTypeId As ElementId, _ levelId As ElementId, _ points As IList(Of XYZ) _ ) As FlexDuct`

Visual C++
`public: static FlexDuct^ Create( Document^ document, ElementId^ systemTypeId, ElementId^ ductTypeId, ElementId^ levelId, IList<XYZ^>^ points )`

systemTypeId: Type: Autodesk.Revit.DBElementId
The id of the HVAC system type.

levelId: Type: Autodesk.Revit.DBElementId
The level id for the flexible duct.

points: Type: System.Collections.GenericIListXYZ
The point array indicating the path of the flexible duct, including the end point.

If creation was successful then a new flexible duct is returned, otherwise an exception with failure information will be thrown.
