Namespace: Autodesk.Revit.DB Class: Edge

Edge.AsCurveFollowingFace

Method

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

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.

Syntax

public Curve AsCurveFollowingFace(
	Face faceForDir
)

Public Function AsCurveFollowingFace ( 
	faceForDir As Face
) As Curve

public:
Curve^ AsCurveFollowingFace(
	Face^ faceForDir
)

member AsCurveFollowingFace : 
        faceForDir : Face -> Curve

Parameters

Parameter	Type	Description
faceForDir	Face	Specifies the face, on which the curve will follow the topological direction of the edge.

Return Value

Type	Description
Curve	It can be an Arc, Line, or HermiteSpline.

Exceptions

Exception	Condition
ArgumentNullException	Thrown when the specified faceForDir is.
ArgumentException	Thrown when the specified faceForDir is not one of the faces for this edge.
