4.1.5.13.1 Spatial Container

“空间容器”概念将空间元素定义为物理元素或直接与空间容器相关的其他元素(如注释或网格)的空间容器。

“空间容器”概念通过_IfcSpatialElement_子类型与所包含元素之间的_IfcRelContainedInSpatialStructure_对象化关系来实现。_IfcSpatialElement_子类型上的逆向关系_ContainsElements_引用所包含的物理元素。

下图展示了应用此概念时使用的通用类和关系。 此外,概念可能对常见或标准化的行业实践和场景具有特殊意义。对于这些特定的使用场景,下表展示了用户可采用的推荐通用使用模式列表。
