IfcDistributionSystemEnum

IfcDistributionSystemEnum

此枚举标识不同类型的配电系统。它用于根据系统的功能以及此类系统内设备的端口来指定系统，以限制连接到兼容连接。

IFC4中的新枚举。

电缆托架的端口可以使用IfcCableCarrierSegment和IfcCableCarrierFitting连接。为电缆托架段和配件键入对象（不特定于特定系统类型的IfcCableCarrierSegmentType和IfcCableCarrierFittingType可能具有预定义类型为NOTDEFINED的端口，这表明此类对象的出现可能会连接到任何其他基于电缆载波的端口。电缆载波的有效枚举与电缆的有效枚举相同，并且可能是：如果所含电缆的端口均为同一类型，则断言。
