Specifies the visibility of a 3DFace edge 2.
Supported platforms: Windows only
Read-only: No
Type: Boolean
You can also use the GetInvisibleEdge and SetInvisibleEdge methods to query or set the visibility of an edge. Because these methods use an index to specify the edge, they are useful when iterating through all the edges of a face.
VBA:
Sub Example_VisibilityEdge2()
' This example creates a 3D Face in model space and allows the user to
' control the visibility of the edges
Dim faceObj As Acad3DFace

point3(0 To 2) As Double, point4(0 To 2) As Double

Edge3Msg As String, Edge4Msg As String
' Define the four coordinates of the face
point1(0) = 0: point1(1) = 0: point1(2) = 0
