Syntax

public class Edge : GeometryObject

The Edge type exposes the following members.

Properties

Name

Description

Public Property
ApproximateLength

Returns the approximate length of the edge.

Public Property
Code Example
GraphicsStyleId

The ElementId of the GeometryObject’s GraphicsStyle
(Inherited from GeometryObject)

Public Property
Id

A unique integer identifying the GeometryObject in its associated non view-specific GeometryElement.
(Inherited from GeometryObject)

Public Property

IsElementGeometry

Indicates whether this geometry is obtained directly from an Element.
(Inherited from GeometryObject)

Public Property
Code Example

IsReadOnly

Identifies if the object is read-only or modifiable.
(Inherited from APIObject)

Public Property
Reference

Returns a stable reference to the edge.

Public Property
Visibility

The visibility.
(Inherited from GeometryObject)

Methods

Name

Description

Public Method

AsCurve

Returns a curve that corresponds to the edge’s parametric orientation.

Public Method
AsCurveFollowingFace

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

Public Method
ComputeDerivatives

Returns the vectors describing the edge at the specified parameter.

Public Method
Dispose

Causes the object to release immediately any resources it may be utilizing.
(Inherited from APIObject)

Public Method
Equals

Determines whether the specified Object is equal to the current Object.
(Inherited from GeometryObject)

Public Method

Evaluate

Evaluates a parameter on the edge.

Public Method

EvaluateOnFace

Evaluates a parameter on the edge to produce UV coordinates on the face.

Public Method

GetCurveUV(Int32)

Calculate a 2D curve that represents the edge in the uv-parameter plane of one of the edge’s faces. The output curve’s direction will follow the parametric direction of the edge, not the topological direction of the edge on the given face.

Public Method
GetCurveUV(Int32, Transform2D)

Calculate and transform a 2D curve that represents the edge in the uv-parameter plane of one of the edge’s faces. The output curve’s direction will follow the parametric direction of the edge, not the topological direction of the edge on the given face.

Public Method

GetEndPointReference

Returns a stable reference to the start or the end point of the edge.

Public Method

GetFace

Returns one of the two faces that meet at the edge.

Public Method

GetHashCode

Gets the integer value of the geometry object as hash code
(Inherited from GeometryObject)

Public Method

GetType

Gets the Type of the current instance.
(Inherited from Object)

Public Method
IsFlippedOnFace(Face)

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

Public Method
IsFlippedOnFace(Int32)

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

Public Method
Tessellate

Returns a polyline approximation to the edge.

Public Method
TessellateOnFace

Returns a polyline approximation to the edge in UV parameters of the face.

Public Method

ToString

Returns a string that represents the current object.
(Inherited from Object)

Remarks

Edges are defined by intersections of surfaces that form faces of the solid. They have arbitrary parameterization that is normalized to [0,1].
