TransformToSynchronousSheetmetal does not work.

[ Edited ]
Hello, Have someone used the command TransformToSynchronousSheetmetal with success? The documentation doesn't have any sample, neither GTAC.

That's my code:

Dim objApp As SolidEdgeFramework.Application = FSolidEdge.CarregaSEApplication
Dim objSM As SolidEdgePart.PartDocument = objApp.ActiveDocument
Dim objModels As SolidEdgePart.Models = objSM.Models
Dim objModel As SolidEdgePart.Model = objModels.Item(1)
Dim objBody As SolidEdgeGeometry.Body = objModel.Body
Dim objFaces As SolidEdgeGeometry.Faces = objBody.Faces(SolidEdgeGeometry.FeatureTopologyQueryTypeConstants.igQueryAll)
Dim objFace As SolidEdgeGeometry.Face = objFaces.Item(1)

Thanks in advance
