Returns a curve that corresponds to this edge as oriented in its topological direction on the specified face.

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 21.0.0.0 (21.1.1.109)

Syntax

C#
public Curve AsCurveFollowingFace(
	Face faceForDir
)
Visual Basic
Public Function AsCurveFollowingFace ( _
	faceForDir As Face _
) As Curve
Visual C++
public:
Curve^ AsCurveFollowingFace(
	Face^ faceForDir
)

Parameters

faceForDir
Type: Autodesk.Revit.DB..::..Face
Specifies the face, on which the curve will follow the topological direction of the edge.

Return Value

It can be an Arc, Line, or HermiteSpline.

Remarks

Evaluating the edge using EvaluateOnFace gives the same result as evaluating the curve returned by AsCurveFollowingFace with a normalized curve parameter. When a Hermite spline is returned, the two evaluated points will be approximately equal.

Exceptions

ExceptionCondition
Autodesk.Revit.Exceptions..::..ArgumentNullException Thrown when the specified faceForDir is nullNothingnullptra null reference (Nothing in Visual Basic).
Autodesk.Revit.Exceptions..::..ArgumentException Thrown when the specified faceForDir is not one of the faces for this edge.
