Autodesk.Revit.DB Opening

Autodesk Revit项目或族文档中的洞口。

语法

1
public class Opening : Element

附注

该对象表示各种不同类型的洞口：

  • 墙中由修订项目中的两个边界点创建的矩形洞口。
  • 由应用于屋顶、楼板、天花板、梁、支撑或柱的一组曲线创建的洞口。
  • 一个垂直的竖井开口延伸到一个或多个水平。
  • 在族文档中的墙或天花板上创建的简单洞口。

根据打开的类型，此类的某些属性将不可用。

这个对象派生自Element基对象，并且支持该对象的所有方法，例如检索该对象的参数的能力。此对象还支持访问结构分析模型，但此功能仅适用于Autodesk Revit Structure。
