IFC Import - Multiple models in same IFC file

[Ben D]

I've been given a structural IFC, containing two submodels in its model tree.  the structural steelwork is in one model, and the trusses and framing are in another model within the same file.  If I open the IFC in Solibri, I can see the elements of both models.  see below screenshot.  the steelwork is in the "Structure 1" model, and the rest in "Building.b.1".

however, when I then import this IFC into Archicad, I can only choose one of the two models to import.  once this has been done, there seems to be no way to access the other model withIn the file and place it within the archicad file.  The only way around this I've found is to duplicate and rename the IFC file, and import it again, choosing the other model.

This seems a bit crazy - I shouldnt have to keep duplicates of the file to access different parts of it.  Is there a way to get archicad to allow you to place different models from within the same IFC?

Any help much appreciated.

I can agree that GS should make AC less OCD about the contaiment and imports both (several) models...maybe with a warning but nontheless import them since this is a common issue.

... if all buildings share the same (or a subset of the) storey stack.

Archicad itself doesn't support multiple-buildings-with-different-height-in-one-file-projects, so why should the import?

Imagine an IFC file of these little boxes:

Would be nice if the IFC import would check the buildings for similar storeys and offer "import all" though.

But until then the 'multiple PLN hotlinks, each with a single building IFC hotlink' seems the way to go.

Maybe this is an additional setting that the Hotlink Manager Dialog should be able to allow the user to set/store/change (which Building within an IFC file to use as the source of the Hotlink).

If you think this is a feature that should be implemented, my recommendation is that you make a wish for it:

If you do make a wish, please post its link in this thread.
