Syntax

C#
public static IList<Curve> GetSplittingCurves(
	Document document,
	ElementId partId,
	out Plane sketchPlane
)
Visual Basic
Public Shared Function GetSplittingCurves ( _
	document As Document, _
	partId As ElementId, _
	<OutAttribute> ByRef sketchPlane As Plane _
) As IList(Of Curve)
Visual C++
public:
static IList<Curve^>^ GetSplittingCurves(
	Document^ document, 
	ElementId^ partId, 
	[OutAttribute] Plane^% sketchPlane
)

Parameters

document
Type: Autodesk.Revit.DB..::..Document
The source document of the part.
partId
Type: Autodesk.Revit.DB..::..ElementId
The part id.
sketchPlane
Type: Autodesk.Revit.DB..::..Plane%
The plane in which the division curves were sketched.

Return Value

The curves that created the part. Empty if partId is not a part or Part is not divided.
