Function GetFirstFaceArray( _
   ByRef Thickness As System.Double _
) As System.Object

Dim instance As IMidSurface2
Dim Thickness As System.Double
Dim value As System.Object
 
value = instance.GetFirstFaceArray(Thickness)

System.object GetFirstFaceArray( 
   out System.double Thickness
)

System.Object^ GetFirstFaceArray( 
&   [Out] System.double Thickness
) 

Parameters

Thickness

Thickness between the faces

Return Value

A separator is needed between the front faces and back faces. Thus, a NULL always exists between the front faces and the back faces.

For example, if there are five faces in the model, then the mid-surface has five faces. To get the five faces:

• Call IMidSurface2::GetGetFirstFaceArray once.

• Call IMidSurface2::GetNextFaceArray four times.

At each call, the data is arranged as follows if there is one front face in the array:  

[Neutral face], [front face], NULL, [back face]
 

If there are more than one front face in the array, then the data is arranged as follows:

[Neutral face], [front face1, front face2], NULL, [back face1, back face2]

To get the next face from the original paired faces, call IMidSurface2::GetNextFaceArray.
