Partial Structure Display option to hide "Core" skins of Composite Structures/Complex Profiles

[g_avila_epicuria]

With today's BIM requirements, engineers and architects are asked to each have their own IFC model with only the elements relevant to them.

In this case, for the “architectural” parts, we are asked to export our IFC model without the structure and other technical lots.
However, when we use composite elements with finishing/technical and structural layers, we can't separate them from the “core” layer, in other words, the structural part.

We're therefore obliged to create structural materials dedicated to load-bearing elements (“STR wood”, “STR concrete”, etc.) and replace them with “empty” material each time we export an IFC, then go back and replace our load-bearing materials. This method is by all means functional, but very artisanal and time-consuming.

However, we have noticed that there is a “partial structure display” function that filters the 3D layers of the model, allowing only the structural elements and load-bearing “cores” to be displayed.
We'd be interested in having the opposite function of this setting: filter and hide only the structural parts and “cores” of elements, so as to have only an architectural model visualization that can be exported to IFC (finishes, cladding, doors, windows, ceilings, etc.).

And just to be clear, we're french and this was translated with DeepL.com (free version), so sorry about the possibles english mistakes.

Thank you for reading and even more if Graphisoft realise this wish

This is a pretty weird behavior, makes sense to also be able to hide core elements, just as we're already able to do so with finish elements.

This is one way we export it in IFC, with "Participate in Collision Detection option". 

Open Building matirials and Participates in Collision Detection "off" for the construction material. 

IFC translator setings Geometry Conversion:
Export only geometries which "Participate in Collision Detection --> on

I hope this is better for now, a coreless model option would be great!

Hi.

It seams a good idea @Moreno.

We'll try it and give you a feedback about it.

Thank you!

Great news, it works like a charm.

The coreless model option would still be great, as you said.

But for the moment it works fine. We just need to be sure all other materials are "on" for the Participate in Collision Detection" and use the right translator settings.

Thank you again
