BBIM - Ifc 4x3 class and predefined type | quick guide for beginners

in General

I meant to prepare something similar to a quick guide to list the use of Ifc class and predefined type of building elements in a model.

Thanks to @antbozz I was able to prepare something for those, like myself, who are struggling with building elements that are not easy to find in the bSDD or similar.

The proposed coding system (columns 'Type' & 'Subtype') is not the main point of the attached table since it depends on the company's standard, it is rather the content of 'Class4x3' and 'Predefined' that in my opinion could be helpful to beginners.

Any feedback will be greatly appreciated
Happy modeling !

    It is hard to see what entities belong to Domain in the Ifc Document. I thought that combining Entity inheritance and Domain would be easier to organize, but do those of you familiar with IFC have a better way to categorize them?
    Is it IFC's development policy not to include Domain in Entity inheritance?

    IfcDistributionElement

    • IfcDistributionControlElement

      • IfcBuildingControlsDomain
        • IfcSensor

    • IfcDistributionFlowElement

      • IfcFlowSegment
        • IfcHvacDomain
          • IfcPipeSegment
          • IfcDuctSegment
        • IfcElectricalDomain
          • IfcCableCarrierSegment
        • IfcPortsAndWaterwaysDomain
          • IfcConveyorSegment
      • IfcFlowStorageDevice

    bridge classification

    I tried to classify (4x3) elements in a bridge, if anybody with knowledge in infrastructure IFC could check if it is somehow correct or needs to be edited, pretty please?

    thanks

    The proposed classification of bridge elements from the BIM for Bridges and Structures TPF study is in this document.
