Aggregated wall

I’m back with another question, which concerns the other approach to the project i am involved with.

Where the first was about getting close to the workflow of the client, this is about a BIM-for-manufacturing approach. To this end i would like to be able to translate Aggregated/elemental wall module into IFC format, similar to the image below. Would this be possible using GG?

I have tried adapting the tutorial file 11-IFC-Elemental wall, but when exported the members are not part of the wall aggregation.

I have included the file i’m currently working on.

How do you assert that the members are not aggregated into the wall element?

If I review the resultant IFC in solibri, it shows this hierarchy.

In IFC, an element aggregated by others is agreed not to have it’s own shape representation, so the attached approach might give a better result.

Hi Jon, i’m checking this in BlenderBIM. I checked the project hierarchy on the left, where wall and members exist in the same branch. But i do see now in the Aggregates tab on the right that the studs are indeed hosted by IfcWall. I strive to have things nested similar to a GH data tree though.

I’m new to IFC at this scale and still in the process of figuring things out. I do see your point on shape representation. I will study your solution.

I also see a lot of interesting components in the IFC Element tab. Shouldn’t IFCElementAssembly come into play when trying to achieve what’s shown in the diagram above? Or IFCRelAggregates for that matter?
