访问折线和3DFace顶点

如何访问折线和3DFace顶点

问题： 如何访问折线和3DFace顶点 (CADNET-88)。

提示： 要访问折线和3D面的顶点，您需要使用图纸中的实体来访问折线或3D面。

示例：

foreach (CadBaseEntity baseEntity in cadImage.Entities)
{
  if (baseEntity.GetType() == typeof(CadPolyline))
  {
  CadPolyline polyline = (CadPolyline)baseEntity;

  foreach (CadBaseEntity childEntity in polyline.ChildObjects)
  {
    if (childEntity.TypeName == CadEntityTypeName.VERTEX)
    {
      Cad2DVertex vertex = (Cad2DVertex)childEntity;
      System.Console.WriteLine("Coords = " + vertex.LocationPoint.X + " " + vertex.LocationPoint.Y + " " + vertex.LocationPoint.Z);
    }
  }
  }
}
foreach (CadBaseEntity baseEntity in cadImage.Entities)
{
  if (baseEntity.GetType() == typeof(Cad3DFace))
  {
    Cad3DFace cad3DFace = (Cad3DFace)baseEntity;

    System.Console.WriteLine("First point = " + cad3DFace.FirstCorner.X + " " + cad3DFace.FirstCorner.Y);

    System.Console.WriteLine("Second point = " + cad3DFace.SecondCorner.X + " " + cad3DFace.SecondCorner.Y);

    System.Console.WriteLine("Third point = " + cad3DFace.ThirdCorner.X + " " + cad3DFace.ThirdCorner.Y);

    System.Console.WriteLine("Forth point = " + cad3DFace.FourthCorner.X + " " + cad3DFace.FourthCorner.Y);
  }
}
