Parameters

document
Type: Autodesk.Revit.DB..::..Document
The document.
systemTypeId
Type: Autodesk.Revit.DB..::..ElementId
The id of the HVAC system type.
ductTypeId
Type: Autodesk.Revit.DB..::..ElementId
The id of the flexible duct.
levelId
Type: Autodesk.Revit.DB..::..ElementId
The level id for the flexible duct.
startTangent
Type: Autodesk.Revit.DB..::..XYZ
The tangent vector at the start of the curve. The invalid or zero vector is ignored.
endTangent
Type: Autodesk.Revit.DB..::..XYZ
The tangent vector at the end of the curve. The invalid or zero vector is ignored.
points
Type: System.Collections.Generic..::..IList<(Of <(<'XYZ>)>)>
The point array indicating the path of the flexible duct, including the end point.

Return Value

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

Exceptions

ExceptionCondition
Autodesk.Revit.Exceptions..::..ArgumentException The systemTypeId is not valid HVAC system type. -or- The type ductTypeId is not valid flexible duct type. -or- The ElementId levelId is not a Level. -or- The valid number of points is less than two. In order to create a flex curve, at least two points are required. Note the duplicate points don't take into account.
Autodesk.Revit.Exceptions..::..ArgumentNullException A non-optional argument was NULL
Autodesk.Revit.Exceptions..::..DisabledDisciplineException None of the following disciplines is enabled: Mechanical Electrical Piping.
