4.1.5.13.3 Spatial Interference

空间干扰关系 概念定义了空间元素(如设施 (IfcFacility & 特殊子类型) 或设施部件 (IfcFacilityPart 具有领域特定预定义类型))跨越专业空间层级分支与其他空间元素发生干扰或接口的关系。IfcSpatialElement 实体应通过其 IfcSpatialElement.Name 属性进行标识,并且应包含一个可选的 IfcRelInterferesElements.InterferenceType 来描述接口或干扰的性质。

一个简单的例子是包含道路或铁路开发项目的桥梁部分。IfcRelInterferesElements 用于语义链接穿过桥梁的道路或铁路的空间段与相关的桥梁段,并指定相关的干扰类型。这种语义关系提供了一个易于查询的连接,用于识别需要跨越道路设计团队和桥梁设计团队等专业的空间元素。空间层级结构的组织方式取决于用户和项目。

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。
