Determines if this edge's topological direction on the Face is opposite to its parametric direction.

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

Syntax

C#

VB

C++

F#

public bool IsFlippedOnFace(
	Face face
)

Public Function IsFlippedOnFace ( 
	face As Face
) As Boolean

public:
bool IsFlippedOnFace(
	Face^ face
)

member IsFlippedOnFace : 
        face : Face -> bool 

Parameters

face Face

The face with respect to which the direction is considered. Must belong to the edge.

Return Value

Boolean
true if this edge's topological direction on the Face is opposite to its parametric direction, false if the topological direction agrees with the parametric direction.

Exceptions

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

Remarks

Outer edge loops on a Face are oriented counter-clockwise with respect to the Face's orientation, and inner loops are oriented clockwise. The topological direction of an edge on a face means the direction in which the edge's loop is being traversed.
