This .NET class wraps the AcDb::PolyMeshType ObjectARX enum.

Public Enum PolyMeshType
  BezierSurfaceMesh = 8
  CubicSurfaceMesh = 6
  QuadSurfaceMesh = 5
  SimpleMesh = 0
End Enum

public enum PolyMeshType {
  BezierSurfaceMesh = 8,
  CubicSurfaceMesh = 6,
  QuadSurfaceMesh = 5,
  SimpleMesh = 0
}
