For some strange reason, I can't see columns and beams register as space boundaries, even when using level 2 in my export. Shouldn't that work? If not, what types can we expect will be in the file?
I'm aware that beams are not room bounding. But as the surface of the beam, can have relation to the room, it would be natural if a area reference was established (FWIW it's predefined as a possibility does in Solibri). The same goes for elements in linked files, where no space boundary relation is exported.
The surface used for establishing the space is exported, both from beams, columns and elements in linked files. So it's a bit strange to be able to find the relation in that aspect, but not in the space boundary.
My reason for asking, is that we need to build our tender material for quantaties, around data that we can reproduce in the ifc file. In this instance, we are looking into finishes related to rooms.

You are right - for some reason the columns aren't being included by default. We'll look into that. For the beams, I'll have to check that - I don't think they'd participate in the shape of the room. If they do, then they should be included too.

Well they aren't room bounding (why a slanted beam, that pass through a room is not room bounding is an open question). As far as I can find and understand material on Space Boundaries, any element is allowed to participate. So an option to either (A) use default room bounding elements or (B) include all building elements could be a wish from me.
This would allow us to either have a file like now, or have all references. I'm guessing that all references will create a larger and to some bloated file. Being able to reference elements related to the room, such as a stair when doing egress checks, would be great. But of cource within the possibilities in IFC.

Hi Troels,
It turns out that structural steel or wood columns in Revit do not have the Room Bounding parameter. I will look into changing that, but for the time being you can edit a concrete column by changing the material and the profile:

It's well known that structural engineers can walk through steel columns but not concrete :)
