G’day all from down under. If I am modeling building assets to be used in an OpenBIM model, it would be logical for me to categorise them as the various IfcElements that they represent (e.g. my 3D door will be an IfcDoor). However, the IFC spec has shortcomings in describing some objects, such as landscaping (yes, I am aware that there is a current discussion about how to extend IFC to accommodate landscape), and sometimes lack the granularity that other classification systems provide.
I’m looking to hear more about how others in the industry organise their OpenBIM asset libraries? Do you:
- Classify your BIM assets under their respective IfcElement
- Classify your BIM asset using another system, such as Omniclass? (which do you use and why?)
- Classify as both an IfcElement type and another system?
And I’m curious as to how people see the overlap between IfcElements and these existing classification systems. As the IFC entity vocabulary expands, will it make other systems like Omniclass obsolete? Will other players in the industry start using IFC types as a classification system?
Would love to hear your thoughts.
