There is a workaround to do this: you need to make separate IFC exports for each layer and one more for the rest of the model.
You can do this by turning 'participates in collission detection' on and off in the building material settings.
So let's say you have a bricks, air-space, insulation and concrete or bricks that make up the composite. You can leave out the air-space in collission detection all together and then make 3 exports showing only those walls for each material and one more export for the rest of your model. You then need to merge these 4 IFC files.
It is not ideal, but the other alternative currently is to model each layer seperately and that is even more work.
It is interesting to see that the need to have these be seperate is not exclusive to Dutch market, unless your project also takes place in NL.
I'm afraid but from what I know you can extract the height and the thickness of the component, but it's still not possible to extract its length (you cannot even in schedules).
In AC25 you can calculate the length "analytically" (out of Archicad obviously) because they added the "Gross Volume" and the "Gross Area" (obviously it's not exactly the same of a property printed out by AC...but it's better than nothing I suppose).
Talking about export settings I just set geometry conversion to never explode elements and in the Data Conversion I choose what I want to export, eg. Components Properties and Materials properties (I attached a couple of screenshot).
This is something i'm really interested in solving. I want to separate the facade skin from the other skins so that I can use simplebim location editor and connect quantities of the interior part of the wall with the "room volume" for quantity take-off.
