    Ignore the python script, just did some experimeting with a cube and alt+d with the python equivalent.

    I am really breaking my head how one would store this functionality in IFC.

    Where would one define in IFC that IFC objects in Blender are linked? In the Propertysets?

    IFC elements would need a special "BlenderBIM tag" or something.

    Then how does one decide which object is the 'origin'?

    Would be very useful functionality for an IfcOpening.

  • Not an expert (but who is), but what about IfcMappedItem?
    See this commented IFC file as an example of how IfcMappedItem works.
