Parameters

FromFrontFaceListDisp

• in-process,unmanaged C++: Pointer to an array of front faces

VBA, VB.NET, C#, and C++/CLI: Not supported

See In-process Methods for details about this type of method. 

SizeOfFrontFaceList

Number of front faces

FromFaceBackListDisp

• in-process, unmanaged C++: Pointer to an array of back faces

VBA, VB.NET, C#, and C++/CLI: Not supported

See In-process Methods for details about this type of method.

SizeOfBackFaceList

Number of back faces

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 IMidSurface3::IGetGetFirstFaceArray once.

• Call IMidSurface3::IGetNextFaceArray 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]

Call IMidSurface3::IGetFirstFaceArray to get the first face from the original paired faces.
