PR: Cannot export model Group as IfcBuiltSystem

[Bootata]

Problem Description

Hi,
I need to export a group of walls from Revit as a IfcBuiltSystem/OUTERSHELL (IFC4x3 configuration).
I've tried creating a model group and used the mapping default parameters available in Revit 2024 to map easily the model group.

In export IFC configuration setttings all entities listed are correctly set to be exported.

In the IFC file there is not the entity IfcBuiltSystem, as hoped.

Is it possibile to export this entity? Maybe there is a way that i'm ignoring to do so?

IFC File header:

Revit Version

2024.0.x

IFC for Revit Addon Version

24.x.x

Windows Version

10 22H2

I've added an item to our backlog to support this in an upcoming release.

Thanks @AngelVelezSosa,
I will add some more information from my tests: it seems like a model group in revit can be exported just as IfcGroup.
Apparently, Revit also cannot export a model group as IfcSystem and IfcDistributionSystem.

I'd expect a few to work, I'll verify now.

[AngelVelezSosa]

I'll add those to the request.
