PartUtilsGetSplittingCurves(Document, ElementId, Plane) Method

Identifies the curves that were used to create the part and the plane in which they reside.

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 25.0.0.0 (25.0.0.0)

Syntax

public static IList<Curve> GetSplittingCurves(
	Document document,
	ElementId partId,
	out Plane sketchPlane
)

Public Shared Function GetSplittingCurves ( 
	document As Document,
	partId As ElementId,
	<OutAttribute> ByRef sketchPlane As Plane
) As IList(Of Curve)

public:
static IList<Curve^>^ GetSplittingCurves(
	Document^ document, 
	ElementId^ partId, 
	[OutAttribute] Plane^% sketchPlane
)

static member GetSplittingCurves : 
        document : Document * 
        partId : ElementId * 
        sketchPlane : Plane byref -> IList<Curve>

Parameters

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

Return Value

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

Exceptions

Exception	Condition
ArgumentNullException	A non-optional argument was null
