This .NET enum wraps the AcDbSectionSettings::Geometry ObjectARX enum. It gives options for section generation. This enum is used to get and set properties for generated section geometry.

Public Enum SectionGeometry
  BackgroundGeometry = 4
  CurveTangencyLines = &H10
  ForegroundGeometry = 8
  IntersectionBoundary = 1
  IntersectionFill = 2
End Enum

public enum SectionGeometry {
  BackgroundGeometry = 4,
  CurveTangencyLines = 0x10,
  ForegroundGeometry = 8,
  IntersectionBoundary = 1,
  IntersectionFill = 2
}
