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

Dim instance As IMidSurface3
Dim Thickness As Double
Dim value As Object
 
value = instance.GetFirstFaceArray(Thickness)

object GetFirstFaceArray( 
   out double Thickness
)

Object^ GetFirstFaceArray( 
&   [Out] 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 and 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 IMidSurface3::GetGetFirstFaceArray once.

• Call IMidSurface3::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 IMidSurface3::GetNextFaceArray.
